The universal unit is nice and works…
The universal unit is nice and works with my one Pro 100 panel. The instructions for the one panel needed more explaination but I finally figured it out. Also it is quite heavy to change out. I am a 67 gal and do work out but changing from horizontal to vertical can be challenging but doable. All in all glad I got and will think on adding another panel which will make it even heavier if need to change out but might be a way to figure on not going from horizontal to vertical with the 2 panels? Worth the money as it is built well.
