RovyVon GL4 Pro (2X Batteries Included) 4-in-1 Rail-Mounted Flashlight with Visible and IR Beams, Adapt for GL and 1913 Picatinny Rails

I’ve been running this for a couple months on my 300BLK PDW and it is stellar for the money. This is definitely not an airsoft laser aiming module.Pros- The IR laser has held zero over several range trips, hundreds of round, and all while being handled less than gently. It is also strong enough to be usable out to 200+ yards. Finally, the slaved green laser makes confirming zero a piece of cake.- The footprint is small and the QD mount is tight (at least for my setup). It is ideal for the 12 o’clock (unless you’re running an A2 style front sight post which does not work), but is usable at the 3 or 9 o’clock.- The toggles work well and are positioned where having a tape switch would be unnecessary.- Front battery loading. Enough said. No need to rezero after changing your battery.- The IR light is definitely stronger with more throw than the VIR II. Might be too strong for small rooms as it oftentimes causes my NODs to auto-gate. For outdoors or larger rooms? Wonderful.Cons- The setting knob is not stellar but you do get used to it (though it is substantially more difficult with gloves).- The white light is anemic. That said for lighting up shadows or clearing a house, it is terrific.- The IR light is a bit floody but not nearly as bad as the VIR II. It isn’t the Vampire but it is more than usable.

Excellent value for product that functions as explained. Feature rich with quality build.

The media could not be loaded. Came with 2 batteries, pretty flood in IR.1 second push to latch on is way too long. Should be double tap like real and clone PEQ15sMount worked fine for me, but I could see it being marginal. It is not adjustable.Zeroing mechanism sticks internally, requiring you to move windage to get the elevation to settle and vice-versa. See video, will exchange.

Good for PCC or Pistol. Not bright enough for a rifle. Good quality. Better than buying the equivalent Surefire. This is made very well. Just like the Surefire that they copied. Chinese products are very high quality now! You get more than what you pay for!

Well made and works as described.Plenty of video reviews and most are positive. Cost was a huge plus.

I like all the features and yes the white light is a little weak but in reality I don’t expect to use the white light much since I already have a great white light now.The selector switch really is tiny but easily manipulated. I will glue an extension onto it one day. But for now it stays selected on IR

I really want to make this a good review or at least give the company some credit because I was very impressed at the beginning. But in the end the unit failed to hold zero for me.The good:First off, the fit and finish, the mount, the laser quality and the overall unit are very nice!The laser and the Ir laser slave function worked very well. I mounted it a .22 and downed 4 pigs the first night I used it. I was very happy and impressed with the unit.Its a pinch heavy for a pistol but also adds a nice weight for a steadier aim.An observation:The lasers are not centered under bore.If you zero the laser at a short distance, say 20 yards, you’re only going to be accurate at 20 yards. At 40 it will be way off.If you zero to say, 200 yards, you have to account for the fact that the laser will be zeroed 1 1/2 inches low and 1/2 inch left at the muzzle. So if you are doing something like trying to hit a tiny pig brain at 20-30 yards with a .22, you will miss the brain if you aim the laser where you want the bullet to go. Thats standard laser stuff, and not a huge deal, but having the laser under bore would have been one less thing to factor in.If you want it for a pistol doing center mass at 10 yards or airsoft, I’m sure Its perfect for you!At this point i would have given the unit 5 stars. With the negatives being that the visible light is pretty weak, and the selector switch is hard to manipulate, especially with gloves. But for the price, very minor details.The Ugly:I mounted it on my Glock 17 and the zero walked all over the place. Put it back on the .22 and it walked there too. Total round count, 14 rounds through the .22, 30 through the 9mm. Started losing zero after the 19th round. Checked the mount and it seemed secure.I will assume I got a bad unit which is a bummer because while it worked, it worked beautifully.Give yours a thorough work out before trusting your life to it.

4 in one is a great feature but not if it doesnt hold zero, falls off under recoil, or wont stay indexed because the rail piece on the inside moves forward under recoil. bad mounting design. used on an apf strike oneupdate: customer service was great and made it right. big thanks to them
