The Natural TELESCOPE Mechanical Mod by SMOKtech - Stainless Steel
Just ordered this and a kick as my back up. Had been searching for a ds mod, but had trouble finding one. coupon code: vaporjoes11percent was a nice little plus.
I really want to pull a the trigger on a stainless steel mechanical mod, but that Smoktech Natural Telescopic isn't the one... I don't like that you can see the batteries through the vents in 18650 mode.
