Just what I was looking for

12 years ago

I had been cycling without a computer for a while, and I must say, this is pretty legit. It basically tells me everything I need, and I'm incredibly happy with it. Certainly worth my money. The only downside I'd say about it is that the setup instructions and operating instructions were pretty difficult. It wasn't all that intuitive to me. Putting it on my bicycle was alright, but the actual functioning of the computer was tricky to understand. After fiddling for a while I finally got it figured out. The same button can do different things depending on whether you click or hold, and depending on what mode you have it on, and there wasn't any instruction manual on how to use each function. Aside from that minor detail that I have worked out within a few days, everything is super smooth!

Solid Performance

12 years ago

The Sigma was easy to install. It is fairly accurate...I probably need to adjust it a bit because the settings it suggests for my wheel size produce a bike speed and distance a little bit faster/farther than what my Garmin Forerunner GPS watch shows. If you don't need cadence and some of the higher end features, this computer will work just fine.

Simple bike use

8 years ago

Had one with a wire-and when I broke that one I decided to go wireless, Once I got this one going it's nice for simple bike use--seems it has to be turned on and off--and if you don't the battery will die--happened to me--So I make the effort to turn it on/off with each use. I am not an avid rider, so I don't need a gadget that is high tech--So far I am liking this wireless device--Was reasonably priced as well-- Would definitely recommend it to another biker who isn't a serious rider

Disappointed

11 years ago

This wireless computer is not accurate which is unlike my wired Sigma BC1009. Tried everything including putting on a new magnet(Sigma accessory). The solution was to buy a new harness and use my wired Sigma BC1009 which is the best bike computer that I have every used.

No, I do not recommend this product
