Used 2 or three different hand squeezers with half a dozen yokes for build and never used pneumatic sqeezer, even though I had one available. I thought pneumatic was too heavy and not as maneuverable to get square on the rivet. I liked the variety of hand squeezers and yokes that I had.
There, one against compared to all the other posters saying to go for it.
