I received my Winter and Spring today.
I did not received my free bonus gift though, I emailed customer service, we'll see what they say about that.
There was more stuff in the box than I expected such as the battery plastic storage box, the carrying pouch and the lanyard.
The winter led color temperature is indeed very warm, almost incandescent bulb warm.
I think I prefer the neutral white from the Spring edition.
On both, you need to unscrew and remove the plastic tag on the battery (proprietary) and the threads were very grippy as you can expect from titanium.
One thing that I may not like so much is the magnet. It is very powerful and lighter steel objects (spare battery, keys,...) come flying to the light and stick to the tail.
