Picked up a Mytee 2 stage booster for my recoil. Pretty impressed with the extra suction. Unit could use a cord relief and a different method for taking the top half off of the bottom half. I have to put a stick in the handle and one in the bottom vac port to twist it off. Outside clamps might be a better way to go. Unit was well balanced for my recoil. Only had 3 specks of sand in the booster after using it. Everything else including all water was sucked back to the recoil. I see on Mytee's site they have discontinued them. Are you just changing the design John?
