Laylax Ambidextrous Swiveling Arm High Capacity Speedloader (Color: Clear)

"Holds damn near exactly 140 rounds. Fills my 140 mags to the last bb plus or minus 1 or 2. Loads like 6 or 7 bbs per pump and it's super compact. The swing out attachment works great and feeds my hi capa mags no problem. I love how the pump arm locks in place a he'll of a lot better then other brands out there. Really recommend.

"Oh man when I got my hands on this thing I thought it was gonna hold up but I was wrong I got a day of use out of it the plunger ended up breaking because it’s to thin and it can’t handle the amount of bbs it’s pushing my thoughts on it are to make the plunger bigger and the feeding port wider don’t buy a cheaper a different Laylax disappointed me for the first time

"Great concept, but has a design weakness. The flip-out lever broke off after loading about 600 BBs. I'm not sure which plastic resin is used, but my guess is that it's clear ABS - not my choice for a component that is heavily stressed in repeated use. (I would have used 30% glass-filled Nylon for that particular component.) The lever design needs more gussets and reinforcement. For 18 bucks I suppose one could consider it a disposable device. I'm returning it for exchange.
I'm finding that a lot of the airsoft products on the market today are not well-engineered.
And material choices leave a bit to be desired.

"Works pretty well, being able to switch the handle from side to side is nice. Since the plunger isn't straight up and down, it can snap pretty easily if you're not careful. Got maybe 2 good days out of it, pretty unfortunate.
