Bought four of the Continental TPU tubes. Two of the tubes would not work with my Leyzne screw head pump.
The tubes are lighter but they do not appear to be more puncture resistant than regular tubes. One had a flaw at the seam, the flatted within weaks of installation. Additionally, they require Additionally patch kits to repair a flat.
The Continental Conti TPU 700c Road/Gravel Tube is light and compact. It takes up very little space in my seat bag. I have not had a flat with 300 miles in so far. Easy to install.
