Ya was funny, I pinged for a refund through Amazon, woke up the next morning thinking I'd watch a few CT training videos so I could get hyped up on their hype before pulling plug.. went to turn the master switch back on, to 'train' with it for a bit at different distances.. Grip laser no turny ony. I don't mean to get too technical here, in Spanish 'el botón, no trabajo'. So, now they are going back for sure. "sure I'll take "Things that break after the first time you use them for $100, Alex." Answer: these things were made cheaply but with a huge price that doesn't match in any way the quality or the benefit of the thing received.. Q: What is most everything I buy lately (EXCEPTION- my KAHR K40), but specifically these CT Laser Grips?" Correct!! aand Circle gets the Square!
