I just bought an Escali Model 136DK. Just received it today as a matter of fact.
I tested the Auto-Off function and it turned off after about 10 min. (Manual says after 5).
However I also bought the A/C power adapter and when you use it, it overrides the auto-off function and does not shut off.
It weighs up to 13 lbs., has a tare function and does Grams, Ounces, KG/gm and LB/Oz.
The platform is removable for cleaning.
Some useless information -- My cell phone weighs 132 grams.
