    My wife and i both use the earlier model of this device on our bikes. The only difference we can see is tht our units are white and mount by twisting in place; and the newer model i black nd slides in place. They are quite accurate, and work well. The setup is fairly intuitive, but the instructions are necessay the first time. Battery life is reasonable, but this varies depending on how much you use the displays. The only issue is the wire that is necessary for the level one device. i don’t mind this, but a lot of people would find this unsightly. I just wrped it around the brake cable and on down the fork and it is not relly a big deal. I would recommend thi product to a friend.

    For someone who rides for fun, this model is perfect. It gives you all the basic information. The set up was a bit challenging for someone who had never set one up before, but nothing Google couldn’t solve. After reading and watching a few videos I had it set up in about 10-15 minutes. The wires down the break line doesn’t look bad. I like this model as it gives me all the basic information I need. Would Recommend.
