This is advertised as a sink and toilet plunger. Don't use it for your toilet. It doesn't work on your toilet and shouldn't be advertised as such. It is a flat head which will only properly suction something if the entire surface you want to plunge is flat. The only reason I bought this was because I was at Target and looking for the cheapest plunger. I saw this one and put it on the ground to test it and I was shocked at how it gripped the floor. Don't buy it.
