I bought this because I needed a 90 degree motorcycle gauge. It's easy to use and works great. I have two criticisms of this. First, the gauge end, the part that actually goes to the hoop, needed to be a bit longer. Second, it's encased in a plastic case, giving it a fairly cheap look. Feeling empty". I think they could make it smoother and/or use slightly better materials. However, I use it every time before I ride a motorbike.
