I purchased and have been using the new 45L semi-round sensor can for just over one month now. It is truly a beautiful addition to my home. I like that the opening is large and that the lid raises quickly. The motor is so quiet it would not wake even the lightest of sleepers - very impressive. I also like that when the plastic liner is installed, it is not visible from the outside at all. A very clean look that matches my stainless steel appliances. Although it can operate on just 4 AA batteries (included - nice touch), I purchased the AC adapter. The can sits nicely at one end of my kitchen island where I do food prep, plugged into one of the outlets on the island, and that makes is so easy to drop in waste without touching the can or having to step on a pedal. Perfect for when my hands are messy. No worries about cross contamination. I definitely recommend the sensor series of cans to family and friends.
