Product review (2 stars): Did the job but
This is the biggest RIP OFF EVER.  Its nothing more than a slab of rubber I could cut myself from a $3 sheet at the hardware store.  Honestly I do this kind of thing a LOT and this is not worth more than $0.89 to buy.  Do yourself a favor and go find a rubber gasket about this size and call it good.  I would risk my floors on it!
