This product has ruined my life. It is absolutely the worst and most incompetent hot water bottle lid enhancer that you could ever have the misfortune of acquiring. It is a disgrace on the respected product category of hot water bottle lid enhancers. A 1/10 review would be flattering for this kind of product. When I saw it being born inside the 3D printer I almost became a supporter of abortion. Never buy this product, ever. Samora's Wonderhouse has effectively managed to make my life a shamble. Thanks a lot, you fruitloops assbasket.
