I'm so excited! I've been experiencing Ego/Riva envy for a while now. I have only used (on a regular basis) a penstyle 801 and a mini M401. I finally took the plunge last night and ordered myself a Riva! Yay for modernizing my vaping habit! I wanted pink really bad but they were out.. (though in hindsight someone told me that instead of 510, I could have ordered 901 with an adapter and got the last pink one). So I went with titanium. Which is also nice. I'll get over it. LOL Can't wait!
