i have the old white ones - still incredibly useful and i use them every day at some point! I weighed my advent calendar choc this morning just to check my estimate of 0.5 was right hahaha
my OH's mum has the next version up - look classier in black and chrome but pretty much exactly the same. They have a few more things in the memory (you can say, type in "chocolate" and it will come up with chocolate, and all you do is put the chocolate on top and press Points.. but i use it mostly for calculating things that arent in the book using the kcals and sat. fat.. brilliant invention they were.. and i've had mine for 4 years and only had to replace battery once.. (oh i was LOST that day! ) xxx
Thanks for this, they sound like they could be really handy so I might just get some
