Query: Short of the mark!

Wanted it as a sink stopper, hopefully to be used in bathtubs, kitchen sink, etc. Tried it in the kitchen sink and for a short time it seem it was doing the job, only to watch the water drain a little later. Not at all what I was expecting for such a simple looking device. I thought somehow it would stick until pulled out, making it an efficient sink stopper. Does perform for a brief interval but nothing like I was led to believe by the positive reviews. Still, it can be used if you are fast enough but nothing to praise its performance. 2 Stars.
