Came across this online the other day. Designed for seniors, disabled, obese or pregnant, they are designed to extend your reach, Although they look pretty much the same, there are a number of models at a range of prices, from $15 to $50. There are lengths from 15.7 in to 23 in. I fit in a couple of the above categories (no, not the last one) so I thought I'd give it a try. Ordered from Amazon, but there are a number of other health care retailers who have advertised them.
