Puncture resistant, nice rolling resistance and light. Rode them from Frankfurt to Vienna with no flats.
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.
