Does anybody else use these?

I'm usually not one to give a bad review to a product, but... MY GAWD. These tubes have been the only thing to genuinely get me angry about road biking. They're worse than 20mph headwinds on a 5% slope.

At first, I thought, "Hey, I'm new to biking. Maybe I'm just running over stuff?"

After today's 75 miler, blowing both the original plus the replacement and then praying I made it home on the third one the last 10 miles... NEVER again. I have about 15 of these lying in a pile since I started (Jan 19). I actually started laughing aloud while installing the 2nd one because I read a cursive, "MADE IN CHINA".

Just had to let my rant loose

On the other hand, the Specialized tubes I installed two weeks ago have run over everything without a hiccup (knock on wood). Didn't someone say all tubes are made in 4 places?
