yeah got to love those DX flashlights. just got the UltraFire SH98 which was a cheap but very good quality XM-T6 light for the $10's or so. i accrual like it more the the S4 1000 lumen because it's focusable, well built, and has a nice weight to it.
Yup, meritline is HK. It's not 1000 lumens, but it is 500-600, which is inline with a lot more expensive flashlights out there. I was actually really surprised by the quality of these... way better than any of the AA zoomies i've had.
Shipping took just under two weeks for me... meritline is very reliable, 40+ orders over the past two years, so far the two times I had problems, they resent me a second flashlight, and for a cheapie headset, just refunded me.
