Another data point--600 mi so far on a new gravel bike with them (Cyclami brand, green, from Aliexpress on sale), mostly paved, and about 160 of those on a couple lightly loaded overnight trips. No flats, but I swapped out the stock 40mm Kenda gravel tires for some cheap and heavy Schwinn urban 38mm tires that have the solid tread thicker than goathead thorn spikes--I've pulled out a few. I weighed the wheels before and after the tire/tube swap, and they ended up lighter overall.
Also have a Schraeder valve (Baen brand...?) one in rear tire of an older hardtail Giant Iguana with a lighter semiknobbby tire, quite thin rubber between the knobs, so I added a cheapo Ali-X PU tireliner to that tire. About 300 mi street riding with no flats yet either. Peak goathead season here is just beginning with the heat, though.
Tried one in a 20x4 fat ebike rear tire, but that was a bust...literally. Maybe a tighter tire would not come off the rim in the first half mile. Yes, I semi-inflate them when installing per the instructions.
