Got mine today, very nice.
What, mine was shipped 2/21/2014, still not here 
It's only been two weeks. I'd say the average would be a week more.
is there a delay to turn the light on or is the delay only for off?
There is a 2s delay to turn on and off.
I just received mine. The build quality is impressive, thread are smooth even if they came dry, square thread.
I thought that the UI would be similar to the Roche M170 but it’s not. No blinky with 3 or 4 click, just HML and ramping with 2 click. The low mode is not really low. The delta between High and Low is not great so the ramping mode is slow, so slow that at first I didn’t noticed it was a ramping mode and as on M170, it ends at the same low value as in HML. On M170 there is more amplitude between high and low so ramping was useful, it’s not the case on the X3.
Except the useless ramping mode, it’s a great 3 mode, side switch C8 like flashlight.
I didn’t test the presence of PWM.
Review will be up tonight
