I wanted to try out TPU tubes for my setup, but I got a slow flat (overnight – one tyre) after just one ride, with no discerneable puncture. However, I left my bike on my balcony for a couple of sunny days before that, which may have pushed temps up past 30 degrees.
Pictured is the flatted tube, seems to be some deformation, but it holds the little pressure I put in it. So it could be a valve issue as well.
In essence: are these tubes f'd? I'm heading off on a week long trip tomorrow, and need to decide if I stick with these or go back to my butyls.

Those look like the same cheap AliExpress tubes I got. They are a bit hit or miss, I had one where the valve was coming out of the side of the tube and not the inside, and another that just never held air. And yes direct sunlight seems to damage them too.
