These tubes are puncture resistant and do not need air every single day. They are not difficult to install and provide a good ride.
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.
Bought four of the Continental TPU tubes. Two of the tubes would not work with my Leyzne screw head pump.
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.
