Never-Clog-Drain

The $20 PermaFLOW Never-Clog Drain seems like a good idea!

With its innovative, self-cleaning design and integrated wiper that removes blockage, PermaFLOW eliminates the need for chemical drain cleaners, plungers, and expensive pipe repairs. This smart alternative to traditional P-traps installs in a snap and even allows for easy retrieval of accidentally lost jewelry and other items.

Amazon has videos of it in action.
