Great quality inner tube.
Arrived fast and fits the tire perfectly. Quality and build are great as well.

Lectric XP-4 Replacement Tube
Had the XP-4 for 4 days and the OE inner tube developed a hole next to the valve stem. Very disappointing. Is this the best we can expect from China?Hopefully, this other Chinese brand will last longer. Giving it 5 stars now, but will edit later if there are any issues.Yeah, they're going to take over the world one day... NOT. Can't even make a bike inner tube.

They hold air.
I gave this product 4 stars because it shipped and arrived quickly and in good condition. I don't have any other comments because they're bicycle inner tubes and what can you say about them other than they hold air like they're supposed to. So far, so good.
