This one actually made me truly appreciate my Blackburn Delphi 4.0, even for all its own issues, it was so much better than this one. This one takes forever to sync after going to sleep and sometimes never does, almost always have to hit a button to wake it up. I've tried adjusting the sensor distance and gap, that's not the issue. What is really awful is the accuracy and slow pace of updates. This reads ONLY IN .5 MPH INCREMENTS! That means accuracy is +/- .5 mph or AS MUCH AS A FULL 1 MPH! Furthermore, updates seem to be infrequent, as is obvious when braking. I'll be at a dead stop for 3-4 seconds before it reads 0 mph. If you are a cyclist who seriously uses a cyclometer for feedback, this one is useless. There is no good way to tell if the gear change or extra effort you just put in are getting you any acceleration... things that are almost intuitive with the Blackburn, which reads to .1 mph and seems to update real-time. Oh, and those godawful rubber bands for mounting... Sure they are easy... until you screw up and one goes flying never to be seen again... And when you are done, the head unit swivels around the handlebars requiring adjustment constantly. This is really only a good cyclometer for casual users and kids. I would never recommend it to anyone who has a serious need for real-time and accurate performance feedback. I will be buying a Blackburn Delphi again soon. Even if it dies again after a year (note, a year for me is 8000-10000 miles, so expect yours to last longer), it's a better deal because it does the job I need. This one is just a waste of handlebar space.

Easy set up and directions and great functionality. No problems what-so-ever picking up the wireless signal.

I bought it about 3 months ago. I put it on my racing bicycle and surprise! It only works around 900km.
In addition, the installation system has a very poor design, it is based on elastic bands!!
The on/off system is really annoying, if you take a five minutes break the computer turns off (which is ok), however when you continue it doesn't turn on! (I mean in a automatically way). So, if you are not taking care of it you never going to get a right reading.
If you are looking for something better try a "topeak". I have one on my mountain bicycle and works great even in hard weather conditions.

At first this speedometer worked poorly, if at all -- the display showed that it only occasionally connected with the sending unit, so all results were bad. I had tried repositioning both parts exactly per the instructions, but nothing worked. I was about to send it back, but called tech support. "Randy" told me to check the battery in the sending unit. They evidently had a bad batch of Mitsubishi batteries, and that is what I found. When I replaced it with a new battery, everything worked fine.

Now I find it easy to use, easy to read, and reliable.

I've had this bike computer for some time and I can't quite relate to all the complaints about it! Sure there's an elastic band (an O ring) to hold the sensor but It works really quite well. At first I was afraid to stretch on it but it is quite strong and fits around my carbon fork which tends to be wide at the top. I like the fact I can switch it from bike to bike very easily. Perhaps some might have issues with MTBs and the sensor moving but for a road bike it is great. You can get the sensor quite close to the wheel without it moving while riding. I've never missed a signal once you spin the wheel a few times. Yes the instruction are sometime a bit shallow but once you got it, it's a breeze. I give it a five star. I'm very happy with it. The only real negative I have is that switching from miles to km (or vice versa) does not convert your past results. I like to understand both but I must do my own conversions.

This is a good little computer, but the users manual absolutely stinks. The instructions are sparse and obscure, especially for setting the wheel size. My question to the Sigma Company: Why go to the trouble of manufacturing and marketing a nice computer but then not give your customers decent instructions on setting it up and using it?

I have tried all of the available mounting options and moved all of the pieces around and have yet to get a consistent link between the computer and sensor. My Specialized Mtn Bike frame layout appears to be significantly different than what Sigma had in mind when they designed this unit. This unit would be nice if the radio was a little more sensitive.

I never owned a bike computer until I bought my Sigma bike computer a few months ago. I now have approximately 1,900 km on it. I say approximately because several times, while riding, it has quit working for no reason. You get off the bike, fiddle with the transmitter, adjust the gap between the transmitter and magnet but still nothing. Then, magically, it starts working again. I've tried changing batteries but nothing works. Even when it is working, you have to remember to start it again if you stop for five minutes.

At the begining this product was working perfectly, to my surprise because this computures usually give you a hard time. This was until I went to to a trial with losts of water and lots of rain, and some water must have gotten into the trasnmiter, because it wont work anymore. The display turns on fine, but wont receive any signal. I believe, these wireless computers are not worth it, for this reason. It worked fine about 3 or 4 times. Lost my money.

it a good product, it make all that i neet. water resisten and you can do many things, good, good.
