It looks better than most gravity fed hoppers , no batteries
Weaknesses:
Doesn't work any better than a gravity feed
Review:
I tested the primo on a Tippmann 98, SP-1, Ion, and PMR
I put 400 rounds through on each gun first a hopper full then two half hoppers.
I was standing still and only shook the hopper if it would not feed at all I did the same with a vl200 and a reloader b for comparison.
I had all the electro guns on semi auto capped at 10-11 bps
The reloader did not stop feeding or chop on any of the guns at all
The primo worked fairly well on the 98 as there is enough kick to shake it a bit but I still had to rattle it a few times but I had almost identical results with the vl 200
The primo was terrible on the on the electros having to repeatedly shake it and it was the same with the vl 200
Conclusion:
If you want n hopper that works and feeds fast and constantly get an electric hopper if you want a slightly better looking gravity fed ( it looks like the Rotor) as a backup get the Primo but its 4 times as much as a VL200 and just looks better thats all
