Does not like water
Automatic Off after 30 minutes
This has been an excellent hopper in almost all conditions. The sound activation works incredibly well. It works so well, I wonder why more hoppers do not utilize it. It is actually sound and vibration activated. Because of this, nearby markers will not set activate the hopper. I have not had it fail to activate under normal paintball conditions.
The feed rate is more than adequate for me. It's listed at the 13-15 bps mark, but I've never gotten that high. I don't need speed as much as I need consistent feeding, and this hopper does that well. It will even feed the last few balls in the hopper, something many other hoppers will not do.
I only have two complaints about this hopper. First of all, it has an automatic off feature that is not selectable. After 30 minutes of inactivity, the hopper shuts off. This feature was put in to save batteries due to people leaving their hopper on in their duffle bag, or breaks. However, as a scenario player, I find myself on the field where I won't fire a shot for over 30 minutes. For this, the feature is annoying at times.
The second one has to do with rain. This hopper does not like the rain. On several occasions, I have played scenarios in the rain. In this condition, the hopper turns itself off and will not come back on without unplugging the battery. I've had no problems in dry weather and consider this minor. Better planning for games possibly involving rain would take care of this problem with a plastic bag.
An excellent hopper at an excellent price. This hopper works great with mechanicals, especially high end mechanicals that don't recoil with enough force to shake a non-agitated hopper. I'm sure it would work with electronic markers just fine, but I don't know if the feed rate is high enough for many users of those markers. I don't know the battery life exactly as I simply change out the battery about once per year as a precautionary measure. The manual suggests 5000 shots, but I know I've gotten well over that without changing batteries.
