DO NOT BUY THE iTOUCHLESS! Oh man, I can't tell you how pissed I am we wasted $200 on this piece of garbage (yes, I said it!). It doesn't come with the required adapter to plug it in, and in order for us to plug it in, we'd have to run an extension cord through the kitchen (helloooo, unsightly). Tried the batteries (takes D-size) and they run out after a few short days. The sensor is very weak so they don't open easily or quickly, and it's inconvenient to push a button to open your garbage can...especially when your hands are full! The bags don't sit well in it, so you have to be sure they are positioned EXACTLY the right way or else they sink down and make quite a mess...seems to happen very easily. These babies fill up fast...there are only two of us and we now have to take out the trash daily. The lids/top and inside are plastic, only the shell is stainless steel so you can't tap a spoon on the inside (if you're cleaning out some tupperware, etc) b/c its too weak. So, in the end this was a very expensive lesson learned. Get 2 garbage cans you like, don't waste your money!
