I have the top deluxe, but wondered too how it compared to the original. I went back and forth wondering if it was worth the extra money, but I figured since it was expensive anyway, I may as well upgrade rather than find it didn't have enough stimulation (I like my hitachi on high). And speaking for that model, it works. The only way I can describe it is to say that when I use a regular vibe it partly numbs me during use, I can feel the orgasm, but the numbness detracts from the sensation. The Eroscillator feels alot like a regular vibrator, but it doesn't numb you at all, so your orgasms are very intense.
I agree, the color and looks dont do much for me, but trust me... once its between your legs, you won't care what it looks like
