Have had my simplehuman step can (38 liter size) for about a month now and it works great! I went with the 'step' model as I don't want to keep replacing batteries. The plastic insert makes it easy to change out the bags. When open, you can see that it has a little red slider thingy (on back right side) that you can push to keep the lid open if, say, you're peeling carrots directly into the can. 
 I do have to wipe it down daily with a sponge to keep clean - true that fingerprints aren't a big issue, but it does get smudges/spots/etc. at times -- normal for any trash can.
