The tork button scheme and display need a complete overhaul. I honestly stopped using them for this reason alone. I also really like the roll dial on the 620. I have noticed something odd on the 620 lately. All of the "new" ones seem extremely twitchy until they are plugged in. When you put the battery in to begin programming them the interface seems to be real jumpy. That was never like that before about 6 months ago. At first I thought I had received a defective timer, but then realized it was happening everytime. Not sure if it means anything, but they changed something about this timer.
