I bought this to replace the Cateye computer that failed after 10 years. I just wanted something simple, easy to read and accurate. This, for the most part, fits the bill. Setting this up was fairly easy, except the clock, the manual uses some rather bizarre terminology that was indicative of being translated from another language. Setting the clock (if that is important to you), requires you know the GMT time zone you are in. Other than that, everything else was straight forward. The screen is easy to read, both day and night, the GPS locks on in 15-30 seconds and is very accurate on the open road. However, if you're like me and ride through heavily shaded bike trails, the GPS, like other GPS bike computers, has a lot of trouble maintaining a signal and provides inaccurate readings. Not really a deal breaker for me, just something to keep in mind if your ride where tall trees obscure the sky. Battery life seems to be good. I ride about an hour a day and it needs charged about every 5-6 days. Read more
