i got a gun a few weeks ago, i've tried it all over the years, TENS, foam rolling, spiky ball, etc. But the massage gun is the only thing that actually works if it's going to help, it does. Had super tight lats/erectors/hamstrings on the weekend and i used it in the morning and by the afternoon i felt 'fixed'. Mine isn't teragun either, was on special on amazon, usually goes for $150 and i picked it up or around $105 ish.
