Query: Save your money...

Just bought one as my old Stanley stud finder died after 9 years of use. This POS thinks all the studs are 6-8" wide on studs I have marked before. Also the livewire sensor is useless and beeps all the time. What the hell are you guys selling Stanley? Don't understand how a company can mass sell such a useless product. Are your QA department a bunch of crackheads? Will not buy another Stanley product from here out.Look at other brands and save your time and money.
