Really sorry to hear that some people are having issues with their Wine
tanks. I've had my black one for a couple months now and love it. It came apart nice and easy, simple twist and glass came off with no fuss. I don't get the whistling on mine, but do get airflow noise on a hard draw. Mine is pretty quiet, I usually take smooth even draws and it vapes beautifully.
I'm using it in TC, 455-485F, with a NI200 coil at 0.15 and get a really nice, moist, flavorful vape. I'm thinking about picking one up in silver as well. I'm looking forward to a V2 with adjustable air flow and top fill, hope SXK decides to make one. I also would like to see a smaller version with a similar design but a little shorter, for smaller mods.
