Nicely done.
Seems to work well with my Vortex Strikefire2. I haven’t taken it to the range yet, but it lines up very well and works exactly as it should.

Nice Bang for the Buck
Well I do agree little on the heavy side, but I will get over that in a hurry! Overall good eye relief and the glass is stunningly clear ! Mounting is good ! 18-inch lbs is a little limp use blue lock tight for sure ! On the rotation of the magnifier to the side seems tight but time will tell ! Hopefully the R&D shop did there homework & testing ! Tried it out today at 50 & 75 and 100 yards with 12" paper target Rev I P/A Cyclops not a bad group ! I believe with a little work and not try to split hairs, I can tighten the group up ! Great Magnifier will be buying another. JustFixIt

Really like it
Good optics, love the quickness and solidness of mount, although would prefer lever QD. Love 4x. 5x isn't as fast. 3x is ok, but 4x gives a nice bump, without too much magnification. Eye bix drastically reduced down from red dot only, but that's an optics limitation, not the product's, which is v etter than most, especially at this price point. Without the magnifier, my stock is fully extended; with the magnifier, it is almost fully compressed. I bought 3rd party caps, which I like. Make sure the magnifier is 1-1.5 inches away fron the red dot, not right up against it. It's engineered for that, and gives better field of view. The magnifier needs to be almost all the way back on the rail. To accommodate my backup flip up sights, I mounted the rear iron between the magnifier and the red dot. Not ideal placement for the irons, but they are backups, not primaries, but with the magnifier folded out of the way, the irons work really well.

Nice quality.
Honestly liked it but returned it because it wasn’t for my build.

Clear and bright. Just a bit heavy.
It's just as clear and bright as my Vortex Micro 3X. The only downside is its weight. The flip to side mount works well.

4x Magnifier is good for target shooting, nothing super precision though
Decent quality magnifier for the price point. Slapped on my rifle and works good with my SIG Romeo 5 red dot. Only reason its getting 3 stars is I get a little bit of a star bust effect on the red dot, nothing crazy but makes my 2MOA dot more like a 4MOA dot which is no big deal as I am not shooting farther than 200 yards. I have no problem hitting a 10x12 plate at that distance. Also the eye relief is not the greatest. I put it and my dot on a riser to help with this and it helped a good amount. Could just be the way I am built, not necessarily the optics fault.

Iam literally over the moon with this magnifier. I could go on how much I love it , but let me just say this, my only regret is that I didn't buy it sooner!
