Review on ⚡️ Revolutionary Rechargeable Leveling Horizontal Li Battery - KINAVEL Unveils Game-Changing Power Solution by Kevin Carr

Overall it was a great purchase. As others have pointed out, the "add-ons" are low quality and not very useful. However, many brands seem to have this problem. If you need wall mounts etc you will either need another brand or (better) a quality universal mounting kit. Performance, quality and accuracy of the main unit are all excellent. It even comes with two batteries in case you use it for a long time or want the battery to always be fully charged. Attaches to a standard camera tripod. I almost got mine back as I couldn't figure out how to turn on angled line block mode and the seller didn't answer my question. Turns out you have to hold the button down for a few seconds when the power is off (the main switch keeps the lasers in place). For less than $100 per level with 4 green lasers that worked perfectly this was a great buy. Used to install a false ceiling that came out perfectly flat.
