Review on Rubber Hole Plug Fits Opening Industrial Hardware by Jonathan Diaz

Through trial and error, I found that this hole plug is an absolute waste of money. The surface is bumpy and rough, making it hard to fit into an opening. The pros? It did fit into the hole, however the quality was far from the expected standard. Overall, i would not recommend this product to anyone in the industrial and scientific field as it wont serve ITS purpose..
