Got the Vapor Storm squonker in from FT a few days ago, and so far it’s been a winner. It is unregulated and fires (according to the specs) down to .05. I don’t have any builds that would verify that, but it’s been performing like a champ on my 0.15 to 0.25 builds. The case is plastic. It’s OK in terms of feel, but a metal case, or a higher quality plastic, would have been much better. But, for $20, I really can’t complain about the case. Both the front and back doors are removable, making battery/bottle swaps a lot easier for my old hands. They are held in place with very small magnets on all corners. Despite the small magnets, there has been no rattles or shifting when I press on the doors. There are small slots on the base so you can use a fingernail to pop the doors off. It comes with a decent silicon bottle, but I swapped it out for a Pulse BF bottle. There was nothing wrong with the stock bottle other than the usual plasticy smell. It needed to soak in some baking soda and water for a few hours, so I popped in the Pulse bottle. The Pulse BF bottle fits so well that I kept it in. Plus the orange goes well with the door color. The stock bottle is clear and has a usable capacity of a tad over 6mls. The 510 is spring loaded and feels very solid. There’s a nice click to the button. The button surround is illuminated (green) and flashes red to indicate various conditions such as low battery, low resistance, over 10 sec puff, over temp, etc. Five clicks to turn it on/off. It also has internal LEDs that flash in various colors when you’re vaping but fortunately, that can be turned off with three clicks. Why do mod makers think flashing lights is a good idea? It takes an 18650 (with included adapter), 20700 and 21700. I’ve been running it with a 20700 and the battery fits snugly enough to prevent rattle, but is still easy to get in/out. There’s a micro USB port on the back for charging. I prefer to use an external charger, but it’s there (and they include a USB cable) should you want to charge in the mod. Need to spend more time with it to determine any quirks or faults, but so far it’s been performing well.
