My scale is a digital one from walmart, I believe it was in the $20-30 range. It says taylor on it, so I assume that's the brand. It works pretty well, I have nothing to compare it to as far as accuracy goes, but it seems relatively consistent.
I weigh myself at least once a day, I would prefer to do it once a week but I can't help it. I have even put it on the top shelf in the back of my linen closet, I still pulled it out to weigh myself the next morning. lol I do try to weigh myself first thing in the morning after uh taking care of business lol but before eating or drinking anything, that way it is the lowest possible number for the day.
