'morning,
I can't speak for their real tents, but I have a pair of their CW early style shelter halves.
Quality is good. Keeping in mind that it's a light-weight cotton drill, not real canvas. Stitching is tight and even. Button holes and grommets are hand worked.
I also got a pair of the end pieces, for times when I needed to actually enclose the "tent". They're a fairly heavy canvas - heavier and coarser weave than the 10oz used in my Panther tents, but I don't know what the actual canvas weight is and if this is representative of what is used in their real tents. Again, good quality, but they got cut up and converted to projects because of the weight. If I remember correctly, the buttonholes on the end pieces were machine sewn, but I could be wrong.
I've ordered a fair amount from BR over the years, but no other tents. Their customer service has always been good.
