Both tubes failed!

Worst tubes I have ever bought both failed due to splitting even though I followed the instructions and only inflated them to 80% for the first month. Avoid!

So far, so good.

My e bike got a flat in the rear tire. I ordered this and it came the next day. Feels good like the stock brand of the inner tube. Good quality so far. Great price, comes with 2 so I have a back up ready.
