I'm very impressed. These sights are everything I hoped they'd be. They are are easy to install and do not wiggle or shift once in place. They have a nice feel and are made out of decent materials. When not deployed they lay flat and do not get in the way. They are very accurate as well. Right out of the box they were centered perfectly but a little low. A couple clicks on the front sight and they were right on target in less than 6 shots. I like these better than the pair of UTG sites I had before I made the switch. These were a great solution since I love shooting with iron sights and my magnified optic prevents me from co-witnessing. I highly recommend these!
