Been vaping on my Speeder for a few days. So far, have used power and TC modes for ss coils. Trying to get used to doing TC to see if I can tell any difference. The gold and white is really nice looking. Love the shape of it, it's all rounded, not boxy... Havent messed with memory or TCR yet, but it's very consistent in TC for ss and I get the same hit every time. Only after playing with it a few days, I can say I am more impressed with this MOD then I am the Smok Procolor. The fire button isnt very clicky, and i dont care much for the up and down being one plastic button, but I can live with the way it is. It seems to be very well made, and the menu navigation is fairly simple. They dont give you much of a user manual.. it's just a single piece of paper folded in half... LOL But there are plenty of Youtube video's if I get stuck trying to figure something out. But for design and hand feel, I still like my Wismec RX3 the best. If only it didnt have bugs, and would do like they advertise it can do (TC), I would be very happy.
