Query: Terrible

This item doesn't work so never buy it. It is supposed to be a 17 function computer. 2 of them work. The time works and the temperature works. The temperature on this computer will usually be 30 degrees Feiranheit warmer than it actually is. it is teribbly designed and never told me speed or distance or anything! This product should not be purchased ever. I only rated it one star because that is the least you can give.
