On the positive side this unit does a good job capturing the weight even of a squirming cat and the memory hold button works fine. I have yet to check its accuracy using calibrated weights, though. The measuring bars help keep my cat from hopping off. On the minus side, it's large and heavy and the bars mean it isn't easily stackable and is easy to break, so it needs to be stored in its shipping box. It takes up a lot of closet space and isn't conveniently portable. The unit I received was also clearly a returned item, not a new item as advertized.
