I'll hold back 5 stars until I give it some more time. First, it's ridiculously overpriced for a "Bluetooth dongle". I know there is firmware and interface software, but it wouldn't cost that much if there was competition. So far, the display is anything but overwhelming. I used other mppt controllers and their "meters" which showed a lot more information. The software installs on my Galaxy A6 tablet but does not connect via Bluetooth. Luckily my LG Volt phone works great with it. The ability to change parameters was the reason I bought this. Well, let's see how it goes. Some of my difficulties were caused by problems with RTFM. "Gosh, the manual even says xyz!" It's up to me. Not Victron. I will update this with him after some time. I can finally love him. I've heard so many good things about Victron that I have very high expectations.
