I recently purchased an Airacuda Max in .22 and it's a laser beam. Absolutely NO complaints here. I have/had a G2 in .25 and it failed 3 weeks after purchase Sent it in for warranty work back in March of this year. After a couple of calls to UX they said they were sending out a new gun. Got it Saturday (finally after 2+ months) and they sent me a used one. (Older serial number than the unit I sent in, lettering yellowed, doesn't hold air.) Called them this morning and informed them of my disappointment. They are still swearing that it's brand new (they don't make the bolt action anymore but that's what I got). I was instructed to send it back and I asked if it would be another 2+ months to receive a replacement. The person I spoke with stated that the G2 in all calibers are breaking and they can't get hold of enough replacement stock out of China.
Personally, I would advise anyone to choose the Airacuda over the G2. I would advise anything over a UX product at this point.
