Heh, I bought the Upton one before I knew any better about prices, availability, etc. I had no idea there were so many of them out there and so cheap. But I had been wanting one and there it was, brand new item. I have never even once used the so called tea functions that are included.
Bottom line, it has served me extremely well. Never has needed recallibrating ... not even a battery. I guess I have had it 6+ years. Simple calculation between daily use and heavy duty use for tastings such as OTTI , it has been used over 7000 times.
It is also a little bigger than most of the pocket types ...
Rarely a tiny leaf particle might cause the weight to "dance" if it manages to get under the platform thingy (technically speaking
), but this is easily remedied.
