The Micro Wireless is one of the newest additions to the Cay Eye Companies long line of trusted cyclocomputers. I had a hard time choosing between this and a more expensive model with heart rate and cadence.

I decided to go with this and purchased a separate wrist HR monitor for around 25 bucks. It saved a good deal of money and could be the solution to one of your concerns.

If you are looking for a basic model without wireless: I suggest checking out the "Enduro 8"; it is cheaper and has most of the basic features (without wireless and backlight).

With that said: I really like this model, it's smaller and has more features than the Enduro; wireless and back-light. It was easier to setup and quickly switches between bikes (with the purchase of a second mount/sensor kit.)

I broke the computer mount in a minor training collision and Cay Eye sent me a replacement mount for free. I suggest you "defiantly get a cat eye", especially at this price; they have great customer service and make an excellent wireless computer.
(I have used this product for six months.) 4 stars

the two things you need in a good cyclometer is that it is small and lightweight, but has all the features you need. This one fills both creteria nicely. The unit is small, but is incredibly easy to read and navigate. and, if you are like me, the last cyclometer you owned consisted of a wire running down your fork -- forget it, this one is wireless. It does the job perfectly, at a great price. 5 stars

The Cateye MC100W is a very nice computer, but suffers from a poor mounting system. The mounting bracket is attached to the handlebar with two tie wraps. There is no way to tighten it enough to keep the computer stable. As a result pushing a button ofter requires two hands, one to hold the computer and the other to push the button. 2 stars

I realize this review may be unfair because I haven't gotten this thing to work. Apparently everyone else loves this thing, but I don't. I agree with the other reviewer about the instructions; the're absolutley horrible. Probably about the worst I've seen. Mounting it was pretty easy, despite the instructions, which seem to have been "written" by someone who hates people. Really, would complete sentances have been that hard? Anyway, once mounted, I've had a GREAT deal of difficulty getting the thing set up and even getting it from km/hour to mph. Mine may be defective as I followed the "instructions" (I use the word loosely here). I did get some of the other settings set. Also, this thing locked into the mount and I can't get it out. It seems cheap to me (and yea, I realize the cost was cheap and I guess you get what you pay for). Anyway, I'm going to throw this thing away (too hard to return and not worth the trouble) and buy something a little bit higher quality. I may come back and edit this review if I ever get this piece of ____ to work. Sorry if this review was unfair in any way but I really don't like this product...
UPDATE: well my friend who is a serious cyclist helped me get this set up (he even had a little trouble) and it works great. i've had no problems with it. i still hate the instructions and the set up. it could be that i was just a little crankier than usual when i was dealing with it though... 2 stars

First off, I am a casual biker so I didn't know if I "needed" this or not. Now that I have it, I really dig it!
Mounting the whole thing took me about 20 minutes--15 to read the pictograph directions and 5 to actually put it on. But that is because I am a little cautious and really wanted to do it right the first time. It actually was quite easy because the installation diagram is very detailed, showing exactly which direction the pieces go, in what order, etc. The computer mounts on the handlebar with double-sided tape and cable ties, keeping it plenty tight and secure. The sending device attaches to the fork the same way and is very ingenious the way it reads off the magnet you attach to the spoke.
A little bit harder was programming it the first time, following the menu flow digrams. But after a few minutes it was very intuitive and I got it set up (with mph, wheel size, etc.) and was ready to take it for a test spin. Which is where its greatness was immediately apparent. I followed a route I knew and the odometer was spot on. The elapsed time pauses when you do, the average and max speeds worked great. In fact, this thing is amazing!
So, bottom line, even if you don't think you need one, you'll soon wonder how you got along without it. Well built, high quality, instructions in about 20 languages, fun to use, and practical. Can't beat it. 5 stars
