The Mapleshade scale is all of those things BUT..
it is also poorly made. The step-tray attached to the original pan was held in place by a 1/4" wide squiggle of hot glue. It was never parallel to the pan and it continued to angle down and change the reading if you left the stylus down for a few seconds. When mine failed I cleaned and reglued it properly but the glue weight was different from the original and I needed to calibrate it. I discovered then that the calibration button sequence described in the manual was for a different model base or some such thing and didn't work. Repeated calls and emails to Mapleshade resulted ultimately in their claiming that it was not in warantee and so they would not support it with proper documentation. YMMV.
