I've been using the Acewell speedo now all summer and have been very happy with its' performance. Have ridden through some pouring rain and it is definately waterproof. I like the two resettable odometers. The "Mode" button is real easy to push with heavy gloves on too. My only complaint is that the green LED signal indicators are a little hard to see under direct sunlight. I originally used the "wrap" method for the tach pickup lead but finally wired directly to the coil. Much less "bouncing" of the bar graph now. I thought of purchasing another from Electrosports to have as a spare if I ever needed it but see that they say "product no longer available"....I wonder if they quit making them or if Electrosports just quit selling them?
