I have done LOTS of searching and experimenting. I still carry my gripper every day. I use the CE3 clearo, fits perfectly with no adapter. I'm in a suit every day, and when I take off the jacket, need to be able to slide something into my pants pocket that won't be a bulge, and won't break. I have found nothing that can take the place of the gripper at just about any price point. It's stealthy and awesome. Have an extra battery in my briefcase, but usually only need one a day to get me back to my full set up in the car. I truly can not think of anything to recommend but another gripper. I'm actually about to order another as a backup just in case.
