I got it last Wed. when I opened it and looked through it I thought it was a defect.It was clear to about 50 yards then from there out it was kind of blurry so I call them back and they said they would send a new one.Well I got the new on today and it seemed a little better but not much.I guess that is why they are cheaper than the rest.Anyways,I tried it out and it works great,seems to be very accurate,ranges down to 6 yards.Very simple to use.I will only use it for bowhunting so I will only range to about 40 yards and maybe use it to sight in my rifles at further distances.But if I were buying one to shoot far with a gun I would spend the extra bucks and get a better one.But for bowhunting it will work just fine.
