Review on Switchable Horizontal Self-Leveling Professional Visibility System by Donnie Boss

It consumes batteries when switched off. I confirmed this after my warranty period expired as the batteries take weeks to discharge. Now I'm stuck with it. Installed a separate switch. Now happy with the level. I also fine-tuned the accuracy when disassembling. This is a good unit overall. good size Works well. The green light is easy to see. I bought an outdoor receiver from a competing brand. The wakeline receiver did not fit properly in the clip mount. Revain duly returned the money to the recipient. I threw it down a 10 foot ladder and nearly broke it. I took it apart again and put the laser swivel mount back into the rubber mounts. Checked, the calibration is ok. Cool little device. If you take out the batteries every time, you avoid the problem of discharge. It's kind of a big request.
