Review on Cobra Products 00320 Plastic Plunger by Billy Mariner

I have an old house with old drains that clog quite easily. I've used rubber plungers with varying success. I recently bought a new low flow toilet that clogs easily. The drain is square/oval, not round. This plunger penetrates the drain more efficiently than rubber plungers. It is also useful for unclogging sinks and sink drains as it provides a better seal. It takes a few uses to learn how to install over a drain or in a drain, but then it's very easy to unclog. I haven't had to use Drano since I got this flask. I recommend it.
