I have always loved their stuff. Started with the naughty mini, which I still have and use 6 years later. I recently got into pod systems which made me remember that at heart, I like .9 at 16 watts mtl vaping. Recently picked up the breeze 2, and I love it despite the 1000 mah and not rewickable coils. The u tech coil desighn uses a wire coil for the initial airflow to the coil, with cotton wrapped around it. It has no contact to the batterie. It just shoots the air from the top of the coil down and around the u shaped coil. Using a coil with no leads, just a tight tube. I'm Able to wrap that with cotton and insert it into the air flow hole on most rtas. Making the TFV8 into a perfect pod type of mtl vape. Also did it with 2 cleito 120s, and now they hit mtl with salt or regular nic so well. Just had to share, peace.
