I ordered a Wurkkos TS10 V2 (4000K, black aluminum) about a month ago but was sent a 6000K version by mistake, so I returned it and received a 4000K replacement two weeks ago. Unfortunately, the positive battery contact button is missing from the head (there’s just a bit of solder where the button should be); it actually works so long as I use a button-top battery and don't shake or jar the flashlight, but I of course contacted Wurkkos to arrange for a replacement. After providing Wurkkos with the flashlight code and a photo of the problem area, Wurkkos sent a replacement, which arrived just the other day. This one had a bad tailswitch, so I screwed the battery tube and tail assembly from the old broken flashlight to the head of the new broken flashlight and -- voilà! -- one non-broken flashlight.
Be advised that the first broken TS10 V2 has the old 0713 firmware, while the second broken TS10 V2 has the new 0000 firmware, which limits Turbo output to 50% FET (vs 100% FET) to prevent burning out the none-too-robust little CSP2323 emitters—this I learned from various jon_slider posts. Like it or not, the new 0000 firmware trades a substantial amount of output for greater emitter safety. Wurkkos has not updated the TS10 V2's information/specs to reflect the lower output associated with the new 0000 firmware. A few Andúril 2 options and default settings have changed as well.
