A good buy
My oura is my second owned e rig outside of my dabtech elite plus and it’s definitely made itself a regular in my life. It’s compact, sturdy, and easy to travel with. It has four levels, but truthfully I only use the med-high and high settings (red/blue). The only downsides would have to be its user friendliness and it personally took me weeks to learn how to draw up smoke within it. Otherwise great e rig.
