    • Exceptional power, features, and price!
Exceptional value for the price. Monstrum is well known for making exceptional products for the price and this light is no exception. The light itself is extremely bright and has an easy to use strobe. The included tape switch, cable routers, m-lok mount, and pic rail mount is an all-inclusive package for quickly setting up a VERY effective weapon light ... show more

    • Special beam cannon
Incredibly bright and holds a charge. I feel terrible for anyone getting beamed in the face with this bad boy. Blinding torch or stunning strobe this thing is the real deal. Charging is also convenient as you dont have to remove it to charge.

    • An outstanding light
Style Name: Picatinny Mount
I’ve bought numerous of these lights now. 2400 lm and the light shows everything I point to. I live in a very secluded and dark area, this light has no problem illuminating any object. ( my primary use so far is out to 160 ft where it throws an approximate 30 degree useable cone, I also have kept it in my truck for 2 months temps between 70 - 135 degrees on a single charge with no problems) Pros - bright. Cons - the light switch on/off bracket is made of a lower quality plastic which has lead to the hand switch coming lose. The other negative is the metal bracket holding the light onto the hand guard is susceptible to vibrating lose. I’m in the process of trying different types of loc tite. Overall I love this product and the price. ... show more

    • Good for the price, not really “duty” grade. Could be excellent
Style Name: Picatinny Mount
Bought it for the mount which is pretty nice. I like the swivel capability while still being Scout compatible. Light is bright, cool in color, lots of flood with a focused beam in the middle. Put it on a Mossberg 940 Pro and put 40 rounds of buckshot through it, no issues with the mount (I did use blue Loctite on all threads) or the light. The light has room for improvements though. 1) the charging port could become inaccessible depending on how you mount it and swivel it. 2) the rubber charging port cover comes loose under recoil. 3) the button tail cap requires 2 clicks to activate, not sure why that’s a thing. 4) the tape switch is integral to a tail cap which means if your tape switch breaks, there’s no way to activate the light. I would like a button in addition to the tape switch. Overall I think it’s good for the price. Hopefully they improve upon it in the next iteration. ... show more

    • Works great very high quality
Style Name: Picatinny Mount
The rail mount is very high quality. Doesn't just have a screw going through rail mount that would knick rails. It has a rectangular piece that goes in between rail segments. Uses high quality torx screws and comes with torx tool. The swivel is solid once torqued down it won't move. Swivel also has threaded steel inserts that won't strip easily. Wish the swivel was reversible. ... show more

    • Perfect light terrible tail cap design
Style Name: Picatinny Mount
Great flashlight, I just hate that you have to click it twice to turn it on with the tail cap. Needs the option to use a single press tail cap pressure pads are not always favorable

    • Very cheap product!
Style Name: Picatinny Mount
I used this light on my AR and after about 100 rounds the light would nolonger turn on. I tried checking the battery and charging the light and still no difference. I noticed if I would press the button multiple times really hard the strobe light would come, but now that doesn't work anymore either. Terrible product! ... show more

    • Good price
Very solid and bright especially for the price. Holds up well even when catching a lot of heat next to a suppressed option.
