Customer service was excellent. Tool arrived on time in perfect condition. I could instantly see the time savings. The app is good, no fumbling with notebooks, and fast data collection is easy.

Where has this been all these years? I have always set sag as best I could by myself. This makes it a total breeze and I created settings for unloaded sport and loaded touring.

How awesome is this? Took me literally a few minutes to use this awesome tool. I had a "home made" tool I was using, which was a huge pain, my wife hated it as well. This was simple EZ and Fast!
