Since I received the indicator it has been used daily. I had no problems with it and it repeats! This is extremely important for those who need to measure accurately or move back and forth to straighten a part. For the price, I wouldn't be heartbroken if I dropped and smashed it, but it feels and performs just like the more expensive Starretts brands. My only complaint, and why I'm giving it 4 stars, is that it's hard to read without high viability ratings. If they could make the igloo and the highly visible Zero Mark colors they would be an even stronger competitor.
