Terrible adjusters - Meprolight MPO-DS Open Emitter 3.5 MOA Dot Pistol Sight with RMSc/JPoint Footprint

Wasn't even applying a lot of pressure and both my up and down left and right screws to adjust my dot have stripped, I am now with a hunk of junk bc I can't zero it at all not to mention the battery isn't locked in like most red dots that cost over 200 bucks it's on the bottom and can easily but rattled out, I do have another sight from you guys that is flathead adjusting and I got that one zeroed with ease it's The mpo-f and I approve of that one, this one however is Dukey do not buy it your better off buying one for 100 bucks off Amazon pretty much same quality and doubt the zero would've even stayed on point even if I did ever get that far
