Thanks for the really quick delivery

Thanks for the really quick delivery of the batteries and charger. ( and a big thank you for the freebies!) my T6 is back up to par w/ new high capacity Lion battery power and the Q5 is certainly an impressive compact back up. My use is daily and reliability is critically important. I have a large collection of available “torches” , but the UltraFire CREE T6 is my go to choice.

Surprised but not unhappy

I thought my order was for just four batteries and was surprised to open the box and find 4 small flashlights with those batteries in them instead of just the batteries themselves. The flashlights are strong for their size so if I don't use them they will make nice gifts I think your batteries are tge best and as an extreme flashlight collector I've had to buy quite a variety of batteries - some good, some mediocre and some just complete junk. Yours are great! I'll be buying more of them from you in the future. Just don't send them to me inside of flashlights again, OK? Thanks and Happy New Year from Las Vegas
