As described

Not very durable .. quickly get punctured

Perfect to replace the tube on my e-bike

Super fast delivery as normal, not used yet but seem strong tough tubes

I like the feel of these tubes and yes time will tell if they are the business. I replaced my original tubes after 2 years because i fill them with slime which goes hard after this time. My original tubes hit a puncture early on but the slime sealed the problem. I did not trust the source of my original purchase so i swapped onto these tubes which so far is good and doing the job so i am very happy and long may it continue. I may have been unlucky with the original and we know the danger of punctures but my mind works on gut feelings and my gut instincts tell me that the swap over to these is a good decision so here we go with them...

I love the quality. Exactly as advertised on Amazon. I recommend this product. The packaging is amazing and the product fits right on my bike. The thickness of the tube is very durable. Thanks to the seller for this quality product.

It was shipped fast. Haven't used one of the tire cubes yet but they look great.
