With this garbage 42L is relatively large and especially it opens with a sensor. It consists of 2 parts: stainless steel container and the black plastic cover. The lid does not give me the good but ultra strong air garbage is guaranteed 3 years. There is also a ring for holding the trash bag. Good point: the batteries are provided and there is a solar collector. Furthermore it is possible to turn off with a switch. It is also possible to force the opening to keep the lid open longer than standard 5s. Moreover it is not noisy.
it's only been two weeks that I have but for now I am fully satisfied. I wait to see if it continues to keep its promises in the long term.
Edit: After more than 4 months of use, still no problems and I have not needed to change the batteries.
