This product was originally an auto-return model, but the battery box tabs are broken, preventing it from powering on. Also, the jig on the cup part is broken, so I've been using it as a putting mat. The mat itself is a very high-quality product. Unlike flimsy, cheap mats, it's made of a material similar to carpet. I measured it with a stimpmeter before, and it's a fast green specification, around 10.5 to 11. Please use it as a putting mat.
