|-Lots of features.|
-One switch that converts between two different valves.
|-Poor built quality, my brand new one stopped working until I realized the battery cover is loose and the battery's not getting full contact. So now I have to push down on the cover for the thing to work.|
-Not really a negative, but there's so much feature, I'll never need or use all of them. Might be useful for pro riders.
|-Get something cheaper if you don't need all the fancy features.|
