Yeah I didn't really find it that much of an issue, it just offers more resistance, as Deedie says, you could just drill an air hole in the base.
Deedie’s comment will explain it
Mrs had two of these. Lid broke on the first one. Second one, the main latch to keep the whole top assembly locked onto the body doesn't catch well at all. I'd say these are pretty sketchy.
I'm sure these are in home bargains and Aldi at about this price, got one myself
I do agree that it has some resistance but I wouldn't call it difficult to remove. I commend you for your solution though, quite ingenious :D
