The quality of this item is disgraceful. The hole where the plug goes is misshapen, and the plug itself is misshapen as well. It does not seal. Sometimes it won't even stay in. I contacted the seller to exchange this for a well-made one, and was informed that i would have to pay return shipping- to europe- before they would swap it out. Folks, the cost of that return shipping nearly doubles the price of the item itself. The way i was spoken to was condescending and curt, as if they were put off that i didn't just accept a damaged product. This is NOT WORTH THE MONEY. In the end, i kept the one they sent and had a new plug fashioned for it, using a wine cork, some files and a belt sander.
