Overall the UTG Deluxe Ergonomic Foregrip, Black, is well constructed, seems durable and fit's nicely. The only thing I am not totally satisfied with is the way it attaches to the weaver rail. It only has one "pin" to tighten and hold it in place. If you don't line the "pin" up just right it can come loose and damage the "pin" itself.
I do think it is a good purchase and like the storage and feel!!

Grip Feels Nice, But does not fit my forearm rail too well. There is about 1/8" of front to back travel when mounted to my Tapco Saiga Fore end Rail.

I was a bit surprised at how big this grip is! Though it makes my AR look a little extra 'butch,' it is a rock solid grip that once in place, will stay put. Installation was relatively easy, but I had to use light taps from a hammer to move it back up the weaver rail to get it closer to my Surefire light.
While I would have been happier with the aesthetics of a Tango Down stubby grip, the shipping to Hawaii from the amazon vendors would have been more than the cost of the grip itself. So for now, UTG will do. Appearances aside, it will definitely do what a grip is supposed to for a shooter!

Put this grip on my new M4 carbine and it looks great. No wobble at all, well made.

Fantastic grip! The thing is comfortable, and is very sturdy. However, the main thing that makes it great is the battery compartment inside. With some quick Dremel work, I can easily fit my 1200 MaH stick type 11.1V Lipo inside the grip, meaning I can use my airsoft gun with ris, without needing a Crane Stock.
