Purchased the air grease gun when I bought the Puma AT-6036 air compressor. Before I opened the grease gun package I could see that the trigger was loose. After I opened it, the plastic part of the trigger was broken. There was no damage to the package and no signs that it had been dropped. Never got a chance to use it, so I can't rate the performance.
