After several uses the small tip that is used to reduce the output has a problem. Both the silicone joints have narrow (I think this is due to washing) so that the tip is more practically and that there are leaks, a system with no screws would have been better rather than a slipcase. Lentonnoir itself is practical with its filter grid senlève that it is flexible and can be folded to take up less space for storage. I may have fallen on a bad run but I do not recommend this article. I'll ask for a refund and see other similar products.
