Strengths:    Great computer, very reliable and easy to set up.

Weaknesses:    The mounting style; both how it mounts to the handlebars and how the computer mounts into the sensor bracket.

Bottom Line:   
It was a great computer however I really had to be very mindful of it on the bike and always make sure it was fully seated into the handlebar mount bracket. You slightly rotate the computer to remove it from the handlebar mount. It makes for a super easy way to remove the computer however it makes for a super easy way to knock the computer off the bike mistakenly. For 6 years I did a good job of not knocking it off the bike until yesterday. I had been riding all day when I looked down to see that the computer was missing. I must have inadvertently tapped it at some point and now it is somewhere on a trail at Enterprise South mixed in with the massive leaf fall we've had. Maybe I'll find it in the spring on a random ride, but I'm going to replace it with another Cateye Enduro 8.

Strengths:    Works perfectly, easy to install, easy to use, display is very clear, battery life is long, works as it should

Weaknesses:    if I had to pick oue I would say that the mount for the magnet is only held on with rubber bands and I can see in time the rubber possibly deteriorating and breaking, otherwise I have found no weakness to this computer.

Bottom Line:   
Fair price for a bike computer that works, has all of the features that I need for my rides and I would say that if someone is in the market for a decent bike computer that works like it was meant to this one fits that perfectly.

Strengths:    Worked great for years. Display was clear

Weaknesses:    Sensor not strong enough. Would like a dual tire size mode.

Bottom Line:   
My LBS gave me this computer when I purchased my bike. I've used it for over three years. I've had too many MTB crashes to count and this computer has just kept going. Display is clear and accurate. All informatin I'd want to see is available. Setting the computer was not a problem. Sigma customer support was great when I needed them.
What I am now looking for that the 906 does not have. 1). Support a dual tire mode, 2). back light, 3). Altimiter, 4). cadence.

Strengths:    Large/clear display, easy to attach/set up, lots of functions

Bottom Line:   
Short of getting a GPS set-up, this should be the one and only comp. you need to monitor your progress or train with in general. My first time adding/using a comp.-took me maybe 10 mins. total to put on my bike. I had to move the sensor a couple of times-was too far away to register-user error :P

Strengths:    Nice display, easy to mount, and real easy to set up. Plus a sleek and nice looking computer.

Weaknesses:    None that I have seen as of yet, but if I come across any I'll update at once.

Bottom Line:   
Not the top of the line, but it is a solid computer with all of the functions you need without going over the top. I've put 30 miles on it already and love it so far.

Strengths:    Easy to install, Easy to read, gives me all the info I need and was not expensive. Seems to be quite reliable.

Weaknesses:    None that I know of yet, but have only had it about a month so far.

Bottom Line:   
So far I think it is a fine little puter especially for the price. Its made in Germany and rarely does crap come from Germany. I will update in several months or if it messes up.

Bottom Line:   
The Sigma bike computers are excellent. Try and find another computer with a display this easy to read.
