SOURCE: Problem changing battery for Conair Thinner Scale TH300

My scale is an older model, "can't locate model# in or outside" sticker on back plate is RH697. Scale was purposely setup so that no one can change the battery but a tech. Back plate had no instruct as to where battery is and the 4 small phillips screws were covered with rubber filler. I scraped off the rubber filler and opened it up, inside was a computer board which I took out (6 tiny phillip screws) to get to the battery (it was the expected 3V) the battery was front and back soldered in. That was enough for me, this company is nothing but a bandit forcing you to a tech (est. cost 45-60$) or to make another purchase. True piracy, I'm throwing it out. Make sure when buying anything that runs on batteries that the product offers ease of replacement, I am disgusted with Thinner.
