I'm using a My Weigh ultraship scale I bought 15 years ago (great except that it uses C batteries and doesn't seem to turn off automatically) in combination with a cheap, tiny .1 gram scale for small amounts.
I don't really see the point in having them integrated if they are still two separate pads on the scale.
Edit: it just occurred to me that the ultraship scale must have an optional auto off more so I googled the manual and sure enough. I'm not sure why I didn't do that earlier.
