I installed and set mine up myself while sitting on my living room floor and itr was easy. I won' t go back to the peep. My form has improved and so has my shooting. I have shot 4 Robin Hoods with it this year already.

The only problem I had was that my Left Non-Dominant eye tried to take over the aiming task. This problem I solved by either squinting my left eye or closing it altogether. I t worked great and I have no more problems.
