I had this for laying a couple of bathroom tile floors in my sons house. I used it for those 2 floors and then haven’t used it since. It has great bright lasers making it easy and true to layout the floor. This will need 4 new AA batteries. I couldn’t find the laser target that comes with it but didn’t use it either so in my opinion not needed. Worked well but just not planning on anymore tile jobs! $100.00 gets it delivered to your door via Priority Mail. Or trade for a LDG LT-100 tuner. Yes I do take PayPal.
