I have a TLR75 that I've used for 6 years now. It is very accurate but you should check it occasionaly to make sure it is calibrated correctly. My only complaint is it doesn't work well in low light. Before I hunt a new stand I go in a few days before and range a few reference points like trees or rocks to judge distances from. Since I do this I usually won't even carry it when I hunt. I plan on buying a laser job mainly because I hunt a cutover where 400+ yard shots are possible.
