Bad – These do not come cheap and I think they are just a waste of money. I mean, a bin is a bin.. why do you need it to be a "smart" bin? A good stainless steel bin with a foot pedal you can step on and open the bin is good enough since it works the same way. You won't have to touch the bin with your hands to open it. And those will definitely save more of your penny! Very innovative and creative. Good that the person would not be touching the bin for hygienic reasons. Will be prone to malfunctions and break downs.
