I bought this for my 92 year old grandfather scale. It is easy to use-even äußest shortly afterwards tap with your foot and wait. The announcement is loud and clear. The footboard nice size to tilt without danger somehow. There is a volume control, which is also for people with lesser hearing is clearly audible on the noisiest stage. The only thing I could complain about is that there is no on / off switch and after the battery Insert the device at every touch is turned on. (We were able to insert only spot the Batterei so because the scale would otherwise have chatted during transport us) Otherwise, as I said TOP !!
