I have just received a key finder from US. It is really fantastic. Mum is always losing her keys and the keys we need for different areas in the house so I tagged them all last night. Mum said she couldn't find the internal door keys so I pressed the location number on my key ring and the internal door keys started beeping. We found them in seconds (under mum's pillow). It really works and you can tag up to 36 items. It's a godsend and highly recommended .
