Doesn't work - Wheeler Engineering Digital Firearm Accurizing Handheld Torque Wrench

Bought this product in March of 2024 and used it to install a red dot on my sig, worked great. I now have another red dot to install on another pistol and I take it out of the box to torque the screws down and it won't turn on so I assume the battery is dead. I get a new battery and it still will not turn on. Very disappointed that some how it is already broken when all it did was install one dot then sit on the shelf waiting for it's next use. Will not buy again.
