Strengths: Loud enough to gain peoples especially car drivers attention.
Weaknesses: Breaks very easily. Doesnt sound when it gets colder out.
Cheap construction. breaks easily. Especially the plastic horn mount clip. (The whole things plastic.) Doesn't sound well when it gets a bit too cold out and becomes even more brittle and bound for breakage in lower temperatures. Usually breaks at the mounting bracket which is molded to the horn. Your bike falls usually the Air Zound will break from any contact with anything. So cheap. I contacted the manufacturer a couple years ago and complained that I was on my 3rd air zound and asked them why they don't make one from aluminum or something? The guy told me that the unit would run around $80.00 if they were to do that. and I said "I would buy one for that price if it were durable like something made from a good durable metal or something similar." Great high volume horn sound concept but this product has not been properly developed. There are probably repeat sales big time for this product, so they dont change it. I bought 3 before throwing in the towel with this plastic unit. I'm done with this piece of junk. Buyer beware. Avoid this chinsy product unless you wish to replace it multiple times. It truly sucks in its present form. Handle it with kit gloves and it will still break on you.

Strengths: It is a wonderful product when it works, loud like it is suppose to be, makes people and cars aware you exist.
Weaknesses: weather extremes, sun makes the handle brittle, and useless, cold makes the sound come out as hiss, rather than thunder like it is suppose to.
Manufacturer, realize that this is not an item that i carry for looks, I carry it for safety, and if the moment when I need a vehicle aware that I'm there if the sound does not come out, you'll have one less client, and a big problem in your hands, What you charge is not cheap, why can you make sturdier, so it last longer, Realize you have a great product, that needs to be improved, don't let go to waste

Strengths: Loud. Easy to fill.
Weaknesses: Mount does not hold all that well. Button fo horn requires you to take your hand off of the brake.
If you ride on the street or bike paths, you need this. Joggers, bladers, cyclists, walkers, all wear earbuds or earphones. This gets through. Car drivers look at you before turning into you. It is soo much safer. If unit could be designed to allow thumb activation with hand on brake lever, it would be more intuitive. A deluxe heavy duty version would sell me.

Strengths: Loud horn
Weaknesses: Plastic tube is thin and fragile. Pumping air into the bottle is awkward and is a weak spot.
A great idea for the vulnerable cyclist in traffic as I am. I have had four but, disappointingly, none have lasted all that long. The handlebar mechanism is badly designed but the manufacturer persists in this design probably because it is cheap and not meant to last. I emailed the company suggesting a change but was not favoured with a response. The whole item is made cheaply and sells relatively expensively which is obviously the way it is meant to be.

Strengths: Very loud. Easy to refill.
Weaknesses: Does not work in the winter -- air hisses but no sound comes out. The mounting clamp is poorly made and the plastic becomes brittle and snaps in the cold winter weather.
I've gone through three of these. The first two iterations were the original model of this horn, and worked in all weather, although the mounting bracket snapped on both. The plastic becomes brittle over time, especially after cold winter weather.
The new version simply does not work in cold (<30 degree) weather).
Strengths: LOUD, simple to mount, simple to use, actually WORKs to get cager's attention
Weaknesses: NONE yet
This horn is great. It is VERY loud (may not even be technically legal where I am). It gets drivers attention when they aren't paying attention, and can give a little reminder yo those who see cyclists, but don't at the same time.

I have ridden with my zound for over 10 years - I wouldn't give it up for anything. Scares stray dogs, wakes up most drivers and lets them know where I am. I only wish I could use my presta pump, all my bikes are presta. Don't let your kids play with it.

Strengths: Like most of the people posting, I use the Zzounds on the bike when commuting on the roads during rush hour. Some drivers have an aggressive attitude of "cars have right of way at all times, including when turning left at an intersection when a bike is going through on the green." The Zzounds horn will stop these drivers, because it gets their attention. The horn will get you noticed, and keep you safer when drivers try to pull out from driveways or parking lots without looking. Highly recommended for commuting cyclists.... If you mainly ride on pedestrian trails or bike paths, this horn might be overkill, because it is SO loud (nevertheless, you can give short "beep" sounds if you want to politely alert pedestrians)
Weaknesses: Does not work in the winter. To be fair, it seems to be a general problem with air horns. If you bring the horn inside to warm it up in the winter, it will work for a few minutes outside in the cold, but soon enough, it stops working. Even at full pressure, all you hear is a "pssffft" of air, but it doesn't produce any honk sound (we need a physicist to explain this... probably something to do with density of cold air, or the cold temperatures changing the shape of the sound-producing mechanism??) After the Zzounds air horn stopped working in the winter, I bought a boat air horn (with an aerosol can), and it showed the same pattern: blasts a loud sound inside in warm air, but bring it in the cold, and you just have the "pssfft" sound, no honk......About the bracket... it is true that the horn comes off very easily. However, if you take a little mini-tumble, it is an advantage that the horn part "breaks" off from the housing, because then you just snap it back on. If it was mounted very firmly, it would have broken off in my most recent tumble (self-caused...foolishly applied front brake on slick snow-covered road, causing wipeout!)...I am choosing to believe that they made it come off easily on purpose (perhaps I am deluding myself..perhaps it is just a design SNAFU?)
Excellent product for city commuters to alert drivers to your presence on busy rush-hour streets...the loud blast of sound gets them to look up, and more often than not apply their brakes. One downfall is that mine won't work in the cold wintery days here in Canada, but that's just one season.

If you are a cyclist or biker using the Delta Air Zounds II air horn AND used the older non-Delta, Made In Toronto, Air Zounds II: Have you noticed any differences in effectivty? I haven't found this in any review, or reviews of the Delta Air Zounds II, but my opinion is that the older Made In Toronto version was instantly effective on reckless drivers, but not the Delta Air Zounds II. I believe that the frequency (pitch?) of the louder Delta Air Zounds is at fault, but this is just my two cents worth opinion. (With inflation, make that 25 cents opinion.) If you bike with Air Zounds II, please chime in. I haven't seen this topic covered in Mountain Bike Reviews, either, so let's talk about it. Biking should be safe, and the older (non Delta) Air Zounds II was excellent.
