I bought this to measure my lean angles when riding my motorcycle. I specially liked its dimensions as it didn't block much of my dashboard.But I had to return it. The numbers changed constantly in split-seconds. I had to take my eyes off the road for an uncomfortable amount of time to get a read.Not its planned use. I happily gave it five stars. If another rider reads this, don't buy it. Keep looking for a meter which has a delayed read once maximum lean is reached.
