Bottom Line:I've sent 3 emails to Sports Instruments via their contact email asking for their support on the ECG5 Heart Rate Monitor and haven't received a response. I purchased 3 of these monitors in December 2004 (two as gifts). I use the heart rate monitor during my swim workouts. During my first five workouts it functioned perfectly well. After that, the monitor did not work.

In subsequent swim workouts: the monitor recorded my heart rate after I showered but before I got in the pool. Once I got in the pool it would not register a heartbeat. If I got out of the pool, it would pick up a heartbeat. Twenty minutes into the swim workout, the monitor would erratically register a heartbeat.

I would appreciate a response from Sports Instruments. I want a heart monitor that will work during swims. If your monitors don't work in the pool, give me my money back.

The reason I bought your product was that comments from other users said that you provided excellent support. Well, where is this great customer service?

Bottom Line:I've owned a "Frestyle" HRM for quite some time that developed a problem early on with the "set" function. The heart rate function and stopwatch always performed flawlessly. Last week, on an internet search, I found this forum and learned my unit was made by Sports Instruments and I learned of Mr. Bill Corliss and the service he has provided to users of this forum. I contacted him by email to see if he had any tricks to make it function properly. Indeed, he did. He emailed me back almost immediately and asked if I would send the unit to him so he could fix it for me. He also requested I send him the transmitter so he could check the entire system and refresh all the batteries. I shipped it off to him only last Thursday and when I checked the mailbox today (the following Friday) it was back already. Apparently the long-standing problem with the "set" button was terminal because I found that Bill had replaced my old Freestyle with a brand new Sports Instruments model. Needless to say, the unit funtions perfectly and I'm back in the HRM business.

Bill, if you read this, THANK YOU, and rest assured if the the time comes I have to replace this unit, I'll most certainly replace it with a Sports Instruments.

Regards,
Don

Strengths:Great price
Many features tha brand that cost 3x as much dont have
Very easy operation
Good display
Weaknesses:Goes out under power lines
Chest strap had to stay exactly in place
Chest strap had to be tight
Similar Products Used:none

Bottom Line:Good heart rate monitor for beginners and people on a budget.
Does go out when strap moves to much or when under some heavy power lines. Also does not work with women who have large chest (does not work for my girlfriend at all)
If your low on money and cant afford a Polar this is a model that'll get you by!

Bottom Line:After using Polar products for 4-5 years, the ECG 5 is a solid change. It is much more reliable than Polar and you don't have to pay $40 to have the battery changed. If you're looking for accuracy with a ton of features...get this HRM!

Strengths:Customer service is A+
Weaknesses:The product itself seems to have inherent flaws in design or construction...or both. See below.
Bottom Line:This is another followup from 11/28/00 and then 4/06/01. I got my HR monitor back from Bill in early April. It worked great......for a week. Literally 7 days. Then, I noticed the "glow" light wouldn't turn off. I tried unsticking various buttons, etc. Wouldn't work. I emailed Bill, he was gracious enough to call almost immediately and offered AGAIN to fix or replace. Said the buttons sometimes get "burrs" on them and stick. Anyway, its race season, and I really don't have the time or energy for this anymore...It costs a week and $10 to Fedex it out...Sports Instruments has fantastic customer service, but I really feel the product needs to be retooled, with heavy emphasis on user input regarding design and usage.

Bottom Line:I purchased this heart monitor on-line appx. a year ago. About 6 months into use, the heart rate display wouldn't work. I replaced the batteries as instructed, and still no luck. I chalked it up to a bad purchase through ebay until I stumbled onto this review sight. Sent my monitor to Bill and within 1 week received a new watch back with no questions asked.

Bottom Line:I would like to send a special thanks to Bill Corliss for the prompt service on my circiut5. Not only was the case (it broke where one of the pins inserted) replaced but he took the liberty of replacing the battery and sent a new watch strap as well. Now that's customer service. BTW the HR has always worked great and has the features of more expensive models from other manufactures.

Strengths:This is a followup to a post 11/28....Bill Corliss from Sports Instruments emailed me, asked me to send my monitor and strap in, and he would either fix or replace. When I (finally) got around to sending it to him, the turn around time was a week to a week and a half. Amazing. Free. Works great.
I always say customer service starts when a problem appears, and in this case, customer service was top notch. They are there when you need them!

Bottom Line:My watch died about the same time my old HR monitor kicked the bucket (black display in the summer heat). I was given $100 gift cert. for Father's day and couldn't decide whether to get a watch or a heart rate monitor. The SI Circuit 5 gave me both! Shortly after purchase, the mount for the band broke when I was strapping the HRM on my bars. I Sent it to SI and quickly received replacement, no questions asked. I use it on the bike when I ride, and I wear it as a watch all day long. Sometimes I monitor my HR at work. I see some really low numbers, especially in boring meetings.

Bike Setup:Lemond Zurich Shimano 105, KHS with XT
Bottom Line:
I used my monitor for about 18 months before the display went blank. I followed the manual and had a watch repair shop replace the batteries but the display was still dead.

I sent off the monitor to Sports Instruments to see if they could fix it. Three weeks later the monitor was Fed Ex'd to my door now functioning with new batteries (again). The repair and shipping was done at no charge.

According to the letter sent back to me by Mr Corliss at Sports Instruments, it is very common for watch batteries to be dead from sitting on a shelf too long.

This is fantastic customer service. I had expected my monitor to be gone for 6 weeks minimum and be asked for $$ to repair and ship it.

I will buy another Sport Instruments. The monitor works well and is backed by its manufacturer. Its nice to know that you'll be able to use it for a few years and not have to toss it out at the first sign of trouble.

Bottom Line:I bought the Circuit 5 in late August, early Sept 2000 after borrowing a friend's Polar. Features seemed comparable, price was right. First the audible alarm failed, then the display started to go. I replaced the watch battery, that didn't help. Then I replaced the chest strap battery, that didn't help. Now the display LCD is all goofed up. I am beginning to think maybe there is only one brand to buy, and that I wasted $100. I never used it swimming, only training runs & bikes and in races. I can't recommend this product.

Submitted by Marlon a Weekend Warrior from Ottawa, Canada
Date Reviewed: July 17, 2000
Duration Product Used:Less than 1 month
Strengths:Accurate, affordable, memory feature with alarm.
Weaknesses:Display scratches easily, backlit feature can be hard to access.
Similar Products Used:None.
Bike Setup:Retro-fitted Trek 1200 with Time carbon fork, ultegra gruppo, and Spinergy rev-x's. The mountain bike is a beat up, 50lb. Sears bike special with bashed-up ritchey cleats as the only upgrade, 'cause I'm sadistic when I do trails.
Bottom Line:I'm coming at this as a completely new HRM user, so bear with me - I'm making comparisons with a Timex Ironman.

All in all, I like the HRM, both as a watch and as a training tool. At the price that I got it at, I think it was a more than fair deal for something that provides more than just a pulse reading. For Canadians and out-of-USA folk, at $US 40-45 from Supergo even with import duties, I'd say it's very good. In contrast, I'd have to pay around $US 60 minimum for a very minimal model HRM in Canada. And that's before 14-15% taxes depending on where you live.

Pros: It's pretty accurate. I checked it's performance against a commercial blood-pressure machine in my local pharmacy, and against my family physician (he's a friend and sports buff too) and the HRM was dead on or very close. The chest strap takes a day or two to adjust to for beginners, but I don't notice it anymore - seems to be pretty comfy. Instructions included were adequate, and the HRM's use is almost self-intuitive; note I say "almost", I still had to refer back to the instructions. The large display is good and visible, and the backlight feature is similar to a Timex "Indiglow" function. The audible alarm and memory features work, and they do their job well. In short, only a small learning curve was needed to use the HRM.

Cons: The display is NOT like an Ironman. Be careful with it, although rubbing toothpaste on the display in a circular motion over small scratches will remove the scratches. Pressing buttons to activate features still disconcerts me at times; the feel is not the same as a Timex watch, but after about a month of constant use, I think I can get used to it. The backlight feature can be a little tricky to activate when you're cycling at night, and doesn't stay on once you activate it - you have to keep pressing to see the display. The watch is water-resistant, but I wouldn't go diving with it. The rubbery watch casing surrounding the LCD display is kind of neat, but picks up dirt easily. It washes off just as easily though - in most cases. Like all watches that come with watch-straps, do be careful of watch-strap stink. And yes, the colour of the watch I got was a bright neon-orange, but on the plus side, when I was wearing it as a watch when clubbing at night, it was pretty trendy and I got a few nice comments:)

Last but not least, addressing concerns with Supergo, I find that the service there is satisfactory. No problems as of yet, but I'll keep my eye out just in case. I'll write back in 6 months with a longevity report.

The HRM gets 5 chilis in value, because it's that good a value for non-USA residents, and 4 chilis in rating, because I can't give it a 4 and 1/2; although not perfect in every way (what is?), it comes darn close according to my needs. If you're looking for a good-value HRM as a training aid, this is it. If you're looking for something more high end, you can find it, but you'll pay a price.

Weaknesses:Funky strap

Similar Products Used:None
Bottom Line:Absolutely reliable, never gives false readings, never a transmitter/reciever problem. Only gripe is that the strap on the reciever works well for attaching to handlebars, but it sucks as a wrist strap. Fortunately, I never wear it on my wrist (my running days are long gone). Batteries are still going strong after 14 months.

Be careful with the receiver - the display is not very abrasion resistant.

Bottom Line:

I bought the Circuit 5 at my LBS for about 120USD because my old reliable Polar Pacer got destroyed in a little altercation with the planet. I didn't really need the backlight feature, but what the hell. I'm super-stoked on the Circuit 5, as it is even better than my old Pacer, comes with a great rubber donut for handlebar mounting, and would made a nifty watch with its velcro band (if I didn't have a Casio DataBank already). The chest band doesn't slip at all, and the transmitter battery is user-replaceable (unlike Polar HRM's). I give this bad boy 5 big ones!
