I purchased one of the RCA units at Wal*Mart for my father and it seemed to work well for his application. Their price was about $20.00 less. While I don't advocate using these devices, if it works for you, then that's all that matters. All home centers carry these units as well, so maybe you can save yourself some shipping time by going that route. I am sure that if it doesn't work, you will be able to return it.
