Review on 📐 Contractors' Self-Leveling CO Z Horizontal Dual Module by Tony Francis

I found this to be a great tool for tiling a shower in an alcove. The device projects a long horizontal and/or vertical red level line. I could see it without the included red glasses. This made it easier for me to work with tiles. I would say the horizontal lines can be moved about a meter up on a tripod alone. When I needed more height, I put the tripod on the cupboard next to the alcove. The price was reasonable and was delivered quickly. So far I've probably had a laser for about twenty-five hours on the original batteries.
