I'd give a 4.5 star - Mueller Optical 1x22x 33mm Quick Shot Waterproof Red Dot Scope

So far I like the sight,nice and bright, reflective coating and the auto adjust feature is very nice,haven't tested the waterproof yet though,I'm weary of wasting money but my only qualm is there's no on off button,unless I'm not seeing it but it's not in the instructions or diagrams if it is on there.physically having to unscrew the cap,place the battery and then screw the cap back on isn't the best thing to be screwing with if you find yourself in a situation where you need to just flip it on ( home invasion, trespassers,etc ) the other option is,is leave the battery in and hope it's still on.if you have the money,it's a good range sight but if your wanting something quick and easy for home defense I'd find something with a switch
