Seems well made.  A little on the tight side
I am very active  5 ft 10 in tall.  and also a professional  mechanic so I have popeye forearms.... Large was painfully tight.  That being said  It seems well made.  I overworked my elbow and ordered this for light support but mainly to remind me no to overdo it while elbow ligaments healed up.  I think it would be perfect for people with average arm sizes.  I measured on the high range for the Large and it is painfully tight /  My advice is to order your size if you are in the lower half of the range,  if you are near the upper half of the range for S , M , L ,  order 1 size up unless you want a very snug fit.
