I have two of them. I have used them to shoot thousands of 3/16" aluminum rivets.
I bought the first one and liked it. I then bought the extended nose piece to get into hard to reach areas.
It works, so i bought the second rivet gun, and keep one with the short nose, and the other with the long nose.
Not as fast as my Pop air gun, but way handier without the air line.
I mostly use aluminum rivets, but occasionally use it to pull 3/16" stainless.
No issues with power for my use. I am surprised how long a 2.0 amp battery lasts.
