I have had a Balanzza luggage scale, bought from Lakeland, for years and it has traveled all over the world with me. Having lost the battery cover years ago it is held together with tape and now looks so shabby that I decided, when the batteries died, to treat myself to a new one. What a disappointment the new one is. It is half as heavy again (131g to the old 86g) and so bulky it doesn't fit into the wee pocket the old one lived in. I decided just to stick to my old one and use the batteries from the new one but the cover is fixed with tiny screws which I have been unable to loosen.
