Works as expected, quite well.
Does what it was designed for which is why I bought it. I'm just developing my project, but once I've settled on the design, I'll probably remove the status LED and make other minor changes to save energy. I will eventually optimize the design for low energy consumption and improved efficiency.

Fine for the price. Little time with the datasheet available online made it pretty clear to use.
Yeah, some documentation would have been nice but the data sheet is available online for the chip.
