Works well when wired into the trigger soleniod.
With a modified to 15V pre-sun revy installed it rocks.
We are using them on Semi-Only-Board Intimidators and believe me, it takes all the feed horsepower you can get!
The ProTeam Products version includes a much better sensor and the adapters to replace Vertical Feed tubes on Angels/Intimidators/Defiants/Millenniums and a few more.
The PTP version also includes an aluminum tube to feed adapter instead of the plastic one with AGD kit.
PTP version also includes a much more adjustable mount.
The difference in profile is a real big thing - even more so with an Intimidator as the feed tube is pretty long and makes the hopper really stick up.
Will eat a single battery pretty quick, so we wire in two in parallel.
We also add a switch to turn it off when not in use - it will kill batteries if left on for over a couple of weeks.
The sensitivity will wander all over the place until motor breaks in if you are using vibration sensor.
Causes huge voids in my pocket trying to feed it and the Timi paint!
It is definately worth the money!
Since it is the only thing like it out there, comparisons are moot.
I would recommend it to anyone.
If you just try it and forget the initial feel and look, you will most likely keep it.
It is the only thing that will come close to keeping up with our heavily modified Intimidators.
We have four of them mounted on our Timis and are happy with all of them.
