Review on 📏 OLI Construction Self-Leveling Cross Line Horizontal Tool by Christopher Pfaffe

My wife ordered 6 custom photos to create a large "collage" on one of our walls. Our house is about 140 years old. Nothing is perfectly square. If I used a traditional bubble level and leveled it to the ceiling, they would be off. When I leveled each other - they were off. I was so upset that "a little bit like that. is no longer the case." I stopped, put it in my shopping cart and refused to try again until it arrived. I hung six pictures in half the time it took, two the first time to hang it up.It's bright easy to use and perfect.I can't comment on durability but in my opinion the one time I used it was worth the price.If he dies tomorrow I would buy it again.
