Unfortunately, customs did not clear the package and was sent back. Received an apology from Miniinthebox and credit received very prompt. My apologies to the seller and a huge thanks to Miniinthebox. Very impressed and will do further business.
These are, as far as I can tell, an excellent battery at a very reasonable price, far lower than any local supplier. Well packed, obviously I cannot test them for longevity in such a brief time, but they so far function exactly as expected.
