I was replacing the exact same model (bought in store at Lakeland) with this.The two buttons were both labelled "Unit" - and the "Unit" text on the button where the power button should be wasn't even straight.Additionally the two buttons were incredibly loose and wobbled about compared to the scales being replaced which were tight-fitting and gave a quality click when pressed.Either absolutely appalling quality control (it had a quality control sticker on it!) at £25 or else...I'm very suspicious that these are knock off, which might also explain the other reviews saying very inaccurate, since the scales (the same model) they were replacing used to be incredibly sensitive and reliable.

Although these have a recommend from expert reviews, they are not accurate, oddly worse after using tare. Can add 5g, may not move, may drop back to zero. Add another 5g, same thing. However without tare when at a few hundred grams, the small increments seem to be recognised. Also auto power off is too quick.
One if you're measuring large amounts, not useful for a few grams at a time.
Plus side, easy to clean and easy to use.

Cannot always detect weight under 10 grams and when it does it is obviously not accurate.
