I needed some decent weighing scales to send my business post with. I wanted it to be both sensitive to 5 grams and to cope with heavy weight, and the ultra ship has done me proud.Simply turn on and wait for it to calibrate, this takes about 8 seconds but feels a lot longer.It can cope with up to 22kg, however the accuracy goes down to 10 grams above 1kg which is fair enough.It isn't that expensive, small compact and comes with a letter holder adapter if needed.If you need it to ignore certain weight e.g. empty mailing bag it can be calibrated for this. It also has an auto shut off that can be disabled and works from main supply and of course it looks sleek as well.
So if you need to weigh a lot of stuff buy it.
