See my sig, i got the same thing on order. Somehow the envelope never reached me, it's now officially declared as lost shipment and they are preparing to resend it (Thanks DD for the great service!!).
Werner, check out my other post for an alternative source. Shipping from China has been insecure lately imho.
Especially for its price, half as expensive as Olight i3!, one opens the gift box and thinks immediately "wow this is a really nice product/quality!". Sells well at the alternative source!!
