I bought this for my husband as he needed a good level and no extra pair of hands. I bought this product through AMAZON almost 8 years ago. After the first month it started acting up, no light, then not leveling properly etc. I called the customer service line servral times and same thing pay the money to fix it even though we did nothing to it. NO MANUFACTURER'S DEFECT warranty for the one year. There is no accountability with this company and this piece of junk they sell. As I see on many reviews of this laser level the same chief complaint. DO NOT PURCHASE. AMAZON should take this off of their website. No Customer Service, No one year maufacturer warranty and just no help at all.
