I finally got off my behind and took a picture of my U-cann and a similar needle-tip metal bottle that I got from fasttech.
I never used the U-cann because the needle was so short and I was worried about leaking. The fasttech version has a longer needle and has a plastic bottle inside. So, it shouldn't be as likely to leak. I don't know because I haven't tried it yet.
