Maybe established instead of long established is a better way too put it. You know Tethrd it's gunna be around a long time(unfortunately). Stacked outdoors? Doubt itDidn't you buy Tethrd One sticks? What is the measure of a long established company?
Cruzr and Latitude are on a similar timeline as Tethrd, with less baggage.
Not to say they won't have problems or anyone should buy anything they aren't confident in.
