It locks securely into the MasterFire, securing the weapon at an advantageous angle for quick deployment and can be set to automatically activate the light and the laser when the weapon is drawn, saving critical time in a crisis situation. Its recoil-proof LED and TIR lens focus 1,000 lumens of light into a smooth, far-reaching hybrid beam with a large central spot and ample spill for situational awareness. Available in traditional red (635 nanometers) or high-vis green (515 nanometers), its 5-milliwatt laser is highly visible to the human eye. With a Mil-Spec hard-anodized aluminum body that’s light, strong and weatherproof, the X400UH will get the point across to any opponent.

Best pillow I’ve ever tried—hands down!
Size: Queen, Number of Items: 2
I’ve gone through a bunch of pillows over the years, but this BETU Cooling Pillow is by far the best one I’ve ever used. I sleep in literally every position—on my back, stomach, and sides—and this pillow works perfectly no matter how I’m laying. It really does have a cooling effect, which I love as a hot sleeper. Just make sure your room is cool too, and it makes a big difference. It came vacuum-packed, but it fully expanded within just a few hours. I was able to sleep on it the same day it arrived, and it was super comfy right from the start. I also washed and dried the pillowcase before using it, and it came out looking and feeling great—no shrinking or damage at all. Honestly, I look forward to going to bed every night now just because of this pillow. It’s supportive, comfortable, and totally worth it!

Excellent pillows!
Size: Queen, Number of Items: 2
This pack came with 2 pillows, one firm and one that was flatter and squishy. I absolutely love the flatter one! Most comfortable pillow I've ever used! The firm one was a bit too much for me, but my husband loves it.

It’s alright.
Size: Queen, Number of Items: 2
Not bad pillows. They are comfortable but mine came with an odd odor, kind of mildewy smell to it. Had to spray it down to tolerate sleeping on it.

Nice pillows
Size: Queen, Number of Items: 2
Have had these a few months and so far really like them! They don’t really feel very cooling, but I also run VERY HOT so it could just be me. The foam holds up well and hasn’t flattened like others I’ve tried. They come very compacted- I was shocked how much they expanded!
