Shot blaster gun

[RTspray]

Found this on ebay, has anyone tried them before, I havent got a big compressor setup so I thought this should be more suitable for a lower CFM output than these suction fed guns. Comments please.

it works on the same principle as the suction gun only gravity instead both pull the grit through past the main air jet .not much diffrent realy. ok for light use if your in no rush but a pressure fed pot is the best and more eficient

The suction guns use a venturi, which needs a lot of air to suck the grit up. I would guess the gravity fed gun would need less air, but as BS says you can't beat a pot blaster for any serious work.
