They're ok. Have one and it's got the storage compartment and the tacky rubber covering. Prefer the TD.

addendum: Just checked the site and the price has gone up since I bought one for half that price! It was a while ago and the only diff. appears to be the tethered cap. Get the TD- you can store a spare bolt in it besides batteries. Same price.

I have one and i like it alot. I have big hands and the other styles like KAC and ect. don't have enough room for my hands. plus i like the storage area.
I picked mine up on the EE board a while back for alot less then what they want for them on that web site you posted.
Here is a picture of mine on my M4gery

If you get a chance you should try the Tango Down Battle Grip. The circumfrence of the grip is much better than KAC's or Falcon's.  There's enough room in the storage compartment to store an extra bolt plus a few other pieces. Has a much better attachment system to the rail also.  The attachment point for the pressure paddle for lights/ lasers is pretty kewl too. A bit on the high-end side price wise for this particular type of accessory ( and worth it IMO)but it is the same price as what Falcon is advertising theirs for. No knock on the Falcon product (still favor their Ergo grips and still have one of their FVGs) but for that price point would definitely choose the Battle Grip.
