Bought 4 tubes all have failed in fairly quick succession. Try another brand.

For a tube that cost $25, I was expecting more. I though I would wait to write a review until I put a few months of use on it and maybe 1000 or 1500 miles on them. I am about 175lbs and inflate my tubes to about 85-90 psi. Initially I was pleased with the tubes and they seem to roll well. What I did notice that was different from my old butyl tubes was that they lost air fairly quick. On my old butyl tubes I would top off the air about every 3-5 days and they lost maybe 10 psi. With the TPU tubes I was having to top off every 3rd day and they had lost 20-25 psi. I thought maybe that was just the way things were with this type of tube. I went to ride the other day and noticed the one tire was completely flat. I pulled the tube and put air in it to see where the hole was so I could patch it and to check if something was still in the tire. There was no puncture, but the air was leaking from where the valve is laminated to the tube. In this location I cannot patch it. I am used to going 1-2 seasons on a butyl tube and rarely get punctures. It has only been half a season and this tube is now in the trash. To me this is a quality control issue that needs to resolved. Maybe I got a bad batch of tubes.

I've now got three inner tubes that have failed around the valve area. I'm unsure how I can get a refund.

Love tpu tubes , swapped back from tubeless on my road bike, but one of the last ones I purchased looses air over night, after emerging in water it was bubbling around where the metal stem is moulded to the rubber , but will still keep using tpu tubes

Great service and product

Shipping took way longer than advertised and I ordered buy 3 get the fourth one free, 2 of one size and 2 of another size. I received 3 of one size and 1 of the other size. I will be sticking with tubolitos and more reliable service.

Good service, product and decent delivery.

Super light, easy to install, and hold air really well. Definitely plan on getting more for spares (they’re so much more compact)

I don't know how to honestly rate these because I got a flat on my first ride using one of these tubes. I bought 4
and put 1 to try on my road bike because I wanted to see if I could tell the difference in ride quality compared to a regular butyl tube. Unfortunately, I noticed it starting to slowly deflate within first 15-minutes. By the time I got home from my short 25-mile ride, it was almost completely deflated. I found a super tiny hole in it when I submerged it in water so that was a disappointing first experience with my $25 tube. I replaced the tube and since then I've gone out on 4 rides since with no issues. I'll admit the ride comfort from these tires are definitely nice so may the problem I had with the 1st one was due to a manufacturer's defect? Well, the jury is still out on these until I put more miles into them. $25 per tube is a lot if issues persist.

Came quick emergency spares so haven’t used

Can't comment on ride quality yet, as not been out on the due to poor weather conditions in the UK.

Usually use other popular tpu tube local to me but they were unavailable so, I ordered these from Australia, quality is on par and have been installed and have about 100km of trail rides on them. Excellent so far.

Very light, it's working fine !

Only complaint tubes were in back order so it took longer to get them. Wish u could use a lock nut in the stem.

Finding the product that is not available in the United States.
Fast international shipping
Robust product

TPU nano tubes have worked in our fatbikes without issue in Canadian winter so far. We are hoping for a -20° C spell of weather to really test the low pressure at low temp operation and resilience.

Super lightweight, lower air pressure without the sluggish feel!

Arrived promptly, product as described - been fine so far.
