We use the Eton kit ( Menvier )now badged Ion
use 30 r and 40 H both have proven them selves ( most of the time ) also Memvier 40 with bolt on wireless all the same periphirels across the range and the new app for 30 and 40 is good and reliable
worth a look at Tec back up not as good as used to be and never see a rep
