"Have used this for stainless steel 4.8 and above rivets. The jaws are lasting really well. These even outperformed a £500+ air riveter when we had a batch of s/s rivets with stems that were difficult to grip in the jaws.
Only issue I have had is a couple of the nylock nuts on the links coming loose but this wasn't a problem to tighten them up."
"Bought this rivet gun as an upgrade to my old lever type gun, however, after second rivet the metal arm broke and rivets got jammed. This is a poorly made product and far inferior to others I have used."
"Brought two, broke two! The lazy-tongue mechanism is insubstantial and gave way at the bolted intersection of the unit. May be okay for small rivets, do not use for 6mm and over. Faithful produce a heavy duty rivet gun, works well thus far."
