Try Chicago Faucets. They are geared toward commercial use, so could be more reliable. Last time I was at their site, you built your faucet component by component, so could choose the look and functionality you want. Not fancy, but solid. I am not sure if they offer battery back up, but it is worth a look.

Nearly every time I'm in an airport men's room, either the touchless sopa dispenser or faucet doesn't work. I work my way down the line; nothing. Whoever thought mixing electronics and plumbing was a fool.

I am about ready to install a Grohe touchless. I have the same problem as Joseph - they can't seem to "see" me and I end up doing frantic hand waving, dancing, etc leading to frustration. Can't WAIT to do that at home too. (these are hubby's idea)

I have normal faucets purchased in reserve.

Not to mention if they are working properly be aware that just a casual pass will get you wet when you don’t want water. On the plus side my faucet always has fingerprints on it so maybe not with a touch less unless they are adjusting the temp then no pluses.

Are you familiar with Tapmaster? We have two in our primary bathroom and two in our kitchen/coffee bar! Do a search on Houzz and you'll find lots of threads. 

They require no power to operate and take about an hour to install. We have both the version for floating cabinets and the euro model on our regular cabinets.

I've used them for over almost 15 years in two different homes. They're great because you can install them on any faucet!
