A very handy little tool for building micro coils. I am completely new to building coils and this little gadget has helped immensely. I get nice tight wraps every time with minimal effort. I built a perfect 1.2 ohm micro coil with 28 gauge kanthal on my very first try. PROS -Comes with 3 different size posts (1/16, 3/32, 1/8) that are held inside the jig with a plug. -T6 aluminum construction -Completely tool free use. Uses reinforced nylon thumb screws instead of Phillips/Flathead screws. -The posts are short which makes attaching the leads to the atomizer a simple process while keeping the coil in place. -Comes with 510 threading in the middle of the jig which functions as a nice base to work on your RBA/RDA. -Convenient for beginners or veterans. -Great for travel due to its tiny size Cons -You can achieve the same result with a drill bit that doesn't cost $22.90 (USA shipping). -Comes with a cheap sticker on the bottom. Rip it off. -Cannot order from their website. Must be done through email and PayPal. More experienced users probably won't find much value here, but I found it extremely helpful.
