Tuxin air cooled oil less compressor (same as Hatsan Spark) from Tuxin store Amazon. Piston broke where it bolts to the crank reciprocating piece. 2 months old, less than 10hrs on it. Tuxing has been very responsive replying in 30min or so. Sending repair parts, see how long it takes to get them. It's a refreshing attitude when a manufacturer has faith in the customer to do the repairs. Warranty will continue. Companies that forbid customer repair during warranty insult my intelligence.
