TPU tubes for #cycling - Yay or Nay? Sources?

Anyone using TPU tubes? Would you recommend them?

I note online Chinese vendors (Temu/Ali) are about half the price of my local bike store for them. Anyone have experience with purchasing/brands for Chinese TPU tubes?

They, apparently, got a huge can of sealant meant for cars and shot that into the valve.

Likely a liter+ in total.

The butyl tube had a 6cm tear so the tire was basically completely filled with sealant.

It didn’t work.
