They're discussed pretty regularly, but mostly in threads about electrician's tools, as that's who they've always been marketed to. They're mentioned in virtually all screwdriver threads around here, too. They're pretty much the go-to for linesman's pliers, crimpers, strippers, nut drivers, and screwdrivers (especially insulated) in that trade.
My uncle worked for them for 30-something years until he died in the 90s, selling them wholesale to big industrial customers in the Chicagoland area and Milwaukee. Obviously, this resulted in my father getting loads of the tools at cost and once, a box of 100 orange Klein t-shirts for free.
Most of the stuff they make is excellent, but the advent of internet shopping brought us cheaper stuff of the same or near quality that we couldn't get before, which makes them a pretty poor choice for quality/cost ratio in today's world...except for the 9" lineman's pliers, imo. I LOVE mine. They're from the 80s and they still feel absolutely perfect. I wouldn't mess around with changing those out, even though I have a pair of Knipex sitting around still unopened.
Unfortunately, not all of their stuff is still made in the US these days. They've slowly started sneaking imports into the lineup.
And no my internet is painfully slow, especially since I am currently through a VPN.
