 Putting them in, there isn't too much difference. But yeah, there are different things you have to think about, whether they're battery-operated or power, certain things like that that you don't think about. And when you get more options or touch-free, for example, it seems like sometimes they can be a little touchy with having issues, but they've come a long way. Can you come out and simply give a bid? Yes, we do. We do free estimates for larger projects, and we're also happy to do a consultation on any size project.
