So, I lose the Vector clip and order two more (one to put under glass - break in case of emergency), and because it's an 18 USD purchase, chose the cheap and slow mail option.
2 to 4 weeks delivery time, they say.
Sigh.
That's a long time to go without Vector.
Three days later they arrive - not three weeks. The order was shipped the same day as I purchased the product, and in a box to protect the clips (eDimensional actually sent my TIR3Pro unit in a soft package)!
Great job, guys, I like being suprised this way.
Yet another reason I recommend TrackIR and NaturalPoint every time someone asks how to make IL-2: FB/AEP/PF more fun.
