Expensive yes,  but having tried a lot of the sensor trash cans, this manual is actually better. Once you tap it it opens easily. The design is very good and classy. Forget all the Nine Stars or I-Touch trash cans. Utterly overblown and they break down easily. This one does the job and you don't have to buy any accessories or batteries or whatever.

Pros: Excellent and durable
Cons: None
