I've had the non internet connected one for a few years, and overall I like it a lot. There've been a couple of maintenance issues, but all in all I was able to fix them myself with youtube tutorials.
Mine tends to go about a week and a half to 2 weeks between emptying it out, and it does smell a bit by 2 weeks. I've thought about rigging it up to have a larger bin, but then I'd have to carry a larger bag of refuse out.
