Okay so I went with the sa-12s the motor shifted within 2 weeks. Didn't stop me though. Jacobs warranty support was so quick and friendly. Got my a new sa-12( i can tell its new cause the old one I saw a slight scratch on the chrome part of the magnet) boom get my sa-12 and I'm already ready to get another. Also the RE I did get as well to compare. Sorry RE your **** but your not the low I wanted. The sxx was a Beast but I tested them at 32,40,45,50 hits and for db .
Not a huge jump but it's a jump none the less
