Not bad at all!
I use them for the chemical service. If you don't want to mess with any of the chemicals, but don't mind using a leaf skimmer and brush once in a while, these guys are for you. My old pool guy used to charge $100/mo for pretty much the same thing. They will put chlorine tablets in your floater or do whatever it needs to maintain the proper chemical balance. I've been using them for the past three years and they seem to do a pretty good job. Good customer service as well.
