I've used at least half a dozen of these guns on welders that I've repaired or restored and they work really well. The grip is comfortable, the cable is flexible, and the back end is a perfect fit. Standard M25 consumables work perfectly, but it's important to note that the liner is an HTP style rather than M25 style. The only thing I've noted is that the consumables aren't quite as nice as what you'd find from big names like Miller, Tweco, Radwell, etc. Since those need to be replaced periodically it's not a big deal, and you're only talking about a couple of dollars worth of parts. With that said, the stock parts do work properly and are completely serviceable. At this price it's not too painful to just keep a spare gun on hand to minimize downtime if you damage the first one...it happens.
