Had one, but it's been a couple years. Maybe two shots before it wouldn't advance the mag. Sent that one back, the replacement was a little better. Sometimes I could shoot a mag, sometimes 3 pellets. I toyed with the 2nd one to no real benefit and sold it cheap (with full disclosure as far I could describe/remember). Hope the new owner had better luck with it than I did but that ended my attempts at anything semi-auto. I was ultimately turned off as much by the retailer telling me to deal with the manufacturer, as I was with the with the manufacturer rep telling me to return the gun to the retailer,
That said, I recall some feedback on the gun that was mostly positive so there is hope.
May look into the Huben or LCS one day if cash allows but def not in the same price range, and very different semi auto functionality.
