The Yeti RDA by Envii is a simple, well constructed atomizer with a two post design that allows for an easy, breezy build. Featuring a thick outer sleeve to assist in heat absorption from the coils so it won't ever get too hot, no matter how much it's used. This is a 24mm device with gold plated internals, large post holes so it can accommodate thick wire and adjustable air flow, this is so easy to use and build on!
