Received my usb from Steve yesterday and it's been working good so far, although my only complaint is that it doesn't screw on the atomizer that well. Like mentioned, it's wobbly and mine screws on at weird angles and I have to straighten it out myself, and I can never get it to be perfectly straight. It still functions, just that it doesn't seem like there's a secure connection between the usb piece and the atomizer. This will be very useful when I'm back in the office
