The product is fine, the quality is right. But you have to keep in mind that there are only trash bags that you can change 5 times estimated per pack. But unfortunately there are no affordable alternative. One can the Litter Locker even with normal garbage bags use but these close the smell is not good enough.
The system is purely to do with the knots in my opinion cumbersome and wasted a lot of bags. Would be nicer if the same system would be a clip with it.
