I left my doctor's office (where they weigh you in your clothes) and went straight to the department store, set down everything I hadn't been wearing or carrying when I was weighed, and tested them till I came up with one that was about the same, without having to zero it to set it. It was an inexpensive spring-type one that sits on the linoleum in my bathroom and gets used periodically. As long is it is in the same place and I step on and stand the same way, it doesn't matter if it is exactly like the doctor's office, it is relative to itself and I can tell if I've gained or lost. (Last year I lost 35, probably gained back with this awful cold weather, but plan to lose the last 20 come spring.)
