From what I've seen there are good LR's and bad ones, mine is one of the bad ones. I have sent mine back twice and the only time I've had good luck was when they mistakenly sent me back someone else's which worked good, I can't say great. I have a MS that works every time, the only thing is change in poi from the weight. I have wasted many rounds because of LR fails. I still own it because I can't sell it to someone without lying about what I really think about it.
