Review on OMMO Self Leveling Vertical Horizontal Controller: Precise Leveling at Any Angle by Bryan Gallardo

The product had some great features and comes with lots of accessories. I really like the battery, which also lasts a long time. I got this to help with the tiling work, but unfortunately it's not very accurate on a horizontal line. The vertical line is good and fits my 8ft level. But the horizontal slope is 1/4 at my 5 foot height. (tried 2 different levels) Def can't use horizontal line to put tiles. If this wasn't a problem then this would be a 5 star product. But since I can actually adjust everything horizontally with it, it doesn't make much sense at the moment. Revision: The seller contacted me about the inaccuracy of the laser, they quickly said they would send another one. Got a new and horizontal laser reads correctly now. From the 6 foot level this is a five star hotel.
