Hmmmm even my shorter original Ultrafire ones give me grief - they are my originals that I've used successfully in all my 18650 torches over the years.
Got warning on that DX link - "Due to new airline safety regulations announced by the ICAO, shipping of “pure power” products to your shipping address is not allowed. SKU:120476"
I'll see if Aliexpress is any better.
