I've seen a lot of pictures that make the olive look more like grey, which isn't as attractive to me, but I've decided to go with black for when I do order it.

After doing some research on CPF, it looks like maybe a batch of the TK10 slipped through quality control. Something about the led assembly being loose, causing it to perform in only 1 mode. I might wait a month or two to order it, but I'm looking forward to getting one!
