Just ducky. No problems to report thus far. Just remember when you do get them, don't pussy-foot around with inserting a fresh mag. Slam the bugger in there and pull down on it to ensure it locks properly. They're not like a Marui or whatever and you won't damage the feed nozzle for the hop-up. And use a good quality BB. I use Metal Tech/Airsoft Elite and they work fine. Other brands may get chopped up by the gun, especially if they're brittle.
Remember as well to perform some o-ring maintenance as needed. 2mm x 7mm for the nozzle and 2.5mm x 18.0mm for the piston. Replace them when feeding becomes an issue (double or misfeeds) or velocity starts to tank. Takes about 5 minutes to change both and costs about $6 or so per cylinder. Viton for M90-130 and order the rebuild kit for the M150. That all the maintenance you should have to do, except a shot of silicone oil in the hop-up every few thousand rounds or so, just like any gun.
