Review on 📏 Enhanced Precision with Leveling Vertical Horizontal Illumination by Jerome Pritchard

The product information on the Revain page says the bottom laser shines 6mm off the ground. In fact, it's not even close. It shines 2 cm above the ground or 20 mm. We bought this while trying to level a concrete floor before tiling. YouTube videos show colleagues using horizontal lasers directly on the surface to highlight high spots; then only grind where you see green. This laser will not help you with that. I messaged the seller via Revain's message assistant asking how they can get the laser off the ground 6mm as they claim. About a week later, ML&SL responded and apologized; They asked me to send it back via Revain so they could have their tech check it out. If you look at it you can see that the base itself is 1/4 inch thick so I almost didn't order it. But I believed their information at my peril and peril, and now they're coming back. I also tested it for accuracy - the bottom horizontal laser deflected 1.75mm at 6m.
