Hi, welcome to the best forum on the internet.
You should post this question in the main area of the forum where it will be seen by all. There are a couple trolls that hang around these parts you have to watch out for and it's unmoderated.
To answer your question, I haven't heard of them, they look nice but I wouldn't buy one for this spec alone.
"Solar Charger
12-60V 12A Max, 600W Max"
That's piss poor in today's day and age, especially for the amount of battery capacity you can add.
What is your skill level? Are you mechanically inclined? Can you connect a positive and negative terminal together? Does series and parallel scare you?
Pending your answers you should consider building your own small system, especially if it's something you're going to rely on when you need it... If something were to go wrong you'd have a much better chance of repairing it because you built it.
