The loader rocks. Had a bit of a personal demonstration at the OC and it's really nice.
In the hand it doesn't feel any different to a Halo, although the back is kinda squared off for the tray that is removable. Yup you don't need to take any screws out to clean the tray, it pops out. There are two modes. one is like a normal sensing modes with pulsing cone turns rather than a spring. Then the second is with the RF chip that you attach to your board (at least one aftermarket board company has signed up to produce them as stock). Yeah it's a little heavier than a Halo but it's perfectly balanced so on the gun it doesn't feel much different, plus you can use a variety of different battery combos with it.
Oh, and it doesn't have a rip drive, just a little button that when you press it it goes into reverse, very neat idea.
On a gun it is very impressive.
