These cans are great! The lids on both open with ease. The only drawback is that the kitchen sized one has a lip around the top that makes it difficult to get a very-full bag of trash out. The bag hangs up on the lip. Other than that, they are exactly what I expected.
The kitchen sized one also has open and close buttons on the front, I guess they are for in case the sensor stops working, I have not tried it out to see if there is a way to force it to stay open for an extended time.
Not sure how long the batteries will last. My toddler LOVES to open and shut them, so it will be a real test of the batteries.
Also, a foggy bathroom will confuse the small can and it will open and stay open until the fog clears.
