This is my first bicycle computer so I cannot compare it, but I like it very much for what it does. To have bicycle speed,average speed,odometer,trip meter,temperature and time on display is a benefit to cycling. All that for the price is good value. It does take a bit of time to figure out how it works. Install was straightforward. After install I was curious as to the accuracy of the device. As I found out,this all depends on the number you enter for your tire circumference in millimeters. Initially I used the included chart. Where I ride there are milage markers and mine was off about 50 ft per mile. This was too much for me. I rode 7 miles with a 350 foot error. Here is how I fixed it to bring the accuracy within the resolution of the device which is approx. 5 ft/mile.Find a flat surface and lay a tape measure down for 25 feet or so. Using a piece of chalk mark the tire and the surface you are rolling on as zero. Then carefully count the rotations of the tire,I did 3. Take that liner measurement along the ground surface and divide it by the number of rotations to get your actual circumference of your tire. The more rotations and longer the distance the more accurate you will be. If you measured in inches, then convert it to millimeters. Round it to the nearest whole number and enter this into the device. This worked great for me.
