Pros: It is really simple. And that is why I like it. Just a velcro strip (good quality one) and a centerpeice that is RUBBER which makes a good grip and offers flexure and shock absorbing properties to the light you mount it to. Suitable for guns and/or bikes..

Cons: I would not use it for my arm, that seems silly as well as causing poor circulation, but whatever fetish you have is possible with this.

Other Thoughts: Not intended to bind personal body parts, but I can see that would give a guy a hands-free lighting system that would be the envy of every lady...

Bottomline: This is a necessity if you have a light and ever needed someone to hold it, and it is also quite lightweight so it won't weigh you down if you carry a few with you camping. They can also be used to tie poles together, or a fishing pole to a mast!

Pros: Very good if you need to attach a small flash light to bike or somewhere else, or to carry extra battery to a bigger flash light

Cons: The picture shows the piece attached to the wrist, but it doesn't work, unless the wrist is of a small child. First, the curve (the opening) is too small) and second, the velcro strip is too short.

Other Thoughts: DX, you may wish to advise the MFG to add one extra (longer size / length) strip. Also, 90 degrees swivel parts could be a great addition

Bottomline: For the money, a worthy product!

Pros: I bought several of these a few orders ago. (Curse you DX... I'm going broke saving money!)
They are simply fantastic.
My primary use is on the front end of my Remington 870 shotgun. I shoot three gun matches and sometimes they are in low or no light situations. It's imperative to have a weapon-mounted light in that situation.
The last time I shot, I put about three boxes (75 rounds) through the gun and the mount was no worse for the wear. The flashlight was still tight and hadn't shifted at all. For those concerned with recoil, I've shot 1oz slugs with the flashlight mounted with no problems. The mount held up and the recoil through a short barreled shotgun wasn't enough to cause the light to come into contact with the gun.
With the way they attach around the mag tube, I get 270º of rotation around the bottom of the gun. They're also really quick to attach. In 15 seconds, I can attach the light to the mount and the mount to the gun.
Simply a great product.

Cons: None for me really. It was $2 and does exactly what I need. I can see how a 90º option would be handy for some people with bikes though.

Other Thoughts: Well, I had three of the mounts and only two long guns that needed flashlights so I did the only reasonable thing. I bought another long gun. Seemed prudent really... didn't want the mount to go to waste and I'm not about to look like an idiot and attach a light to my arm.

Bottomline: What's to lose at the price? I chanced it and they're great.

Pros: Built well, "hook and loop" fasteners appear to be good quality. Block is not plastic but instead more rubbery.

Cons: Would be nice if DX would also offer this in the "perpendicular" model where they two troughs are offset 90 degrees from one another. I.E. you could then use this on bike handle bars.

Other Thoughts: Seriously why would you strap two flashlights together, or to your arm??

Bottomline: For the price the build quality is excellent and the fact that the body is flexible means it can accept an object with slightly bigger diameter than it looks like it would take.
