Beautiful but sometimes annoying trash

The -:
- The optical sensor is sometimes downright annoying: as soon as you pass too close to the trash, it opens unintentionally spreading smells; in a small kitchen, it is a disability; I think I'll put a dot sticker on the sensor.
- It has the disadvantages of all the high and narrow bins: the appropriate bags are scarce and expensive, the output of the bag is often difficult if well filled (suction effect)

I still have not found the usefulness of flexible metal hoop that was inside. If anyone can tell me, I will not die idiot ;-)
