I hoped that I could measure baseboard with this laser. I figured that if it was within 1/8" at 64' it would be within a 1/32 at 8'. Not so. At every distance I measured it was off by 1/8", break out the caulking. This thing would work fine for a flooring estimator, measuring cheap blinds for a rental, or measuring for a backyard fence. I'll keep it. If you want something useful to a carpenter, look elsewhere.
