Got one today in clear plastic gift box secured on foam recess and tied with red ribbon. No spare O’ring and operation or instruction is non-exist. Try to use the ribbon as lanyard?
Put the empty cell holder body to reach for strong magnet, absolutely immunity.
Found the tissue free of aluminum/metallic dirts after rubbing the lubricated thread; a vague touch of friction typical to titanium felt.
Overall polishing work is O.K. but with extreme fine hairline traces, tail portion with very small lanyard hole is surprisingly good up to perfect mirror finish grade.
Normal dry AAA cell works fine with small diameter positive pole. LiIon cell on hand has large top and the rim strikes on the raised up electronic components on the driver board and therefore impossible to make contact. Unless one could find LiIon cell of proper pole size or with proper modification, do not push hard. No spring found on head and tail ends inside except a sponge ring perhaps for protecting the driver board.
Fatlokwok, can you post a link to the one you purchased? Was it the $38 version from the official site? the $20 version from the official site? or the KD version for $20.44?
