This was my first electric hopper. I bought a Tippy 98 with R/T, soI needed to get one, and this held more paint, so I decided to get it.
The sound activation works fine on my Tippmann and various low-end guns. But I used it with my Ion and 'Cocker, and they were too quiet! So half the time the paddle wouldn't agitate, and that screwed me over quite a few times at a scenario game before I got an Eggy.
I didnh't care about the LCD screen, and it didn't really seem to do any good. The sensor option worked a little, but not noticably.
The feedneck is small. It is too small for a Tippy 98's feedneck, so if you have one and are going to use it on a tippy, then you need electrical tape, duct tape, whatever tape.
It's a good first hopper, but it dosen't work with the higher end/quiet guns. So only get if you have something loud, like a Tippmann or Spyder.
With the LCD TSA it should be possible to adjust the sound activation sensitivity to the point that it will be set off by even the quietest marker. On mine, the adjustment is so wide that at the most sensitive setting, the loader will spin continuously, as the sound of the motor will keep activating the loader.
