I have the original hitachi, a fairy wand, and another cordless wand. First scratch the cordless one. Its completely useless and barely vibrates. Even brand new and with new batteries it sucked. But i needed it for a shower show so whatever, cant return it.
The fairy wand gets the job done just fine. Its smaller and not as powerful as hitachi but thats a plus for a lot of girls. After a hitachi use (even on low) it makes your skin all red and can at times leave a "burning" feeling. Its basically the leftover effect from the super strong vibration on the skin. You feel numb after, then burning feeling sets in after a bit. If you use a hitachi for extended periods of time for shows (high/low controlled member shows, multiple times a night, etc) you're gonna be sore as fuck after. To the point you wont wanna touch it the next day, or days. And youll walk funny lol. That sucks when it's part of your show and you want to keep using it. The fairy however never leaves a burning feeling, or redness. It doesnt shake your whole pelvis but just the spot you touch and because it is gentler in the vibrations you arent left feeling numb, no burning feeling, and can be used multiple times a day no problem. The hitachi on high is just ridiculous to me mind you. Like rocket ship me off the couch haha. The mini even on it's highest setting isnt as strong as a hitachi on low, but it still gets the job done every time.
As far as attachments if you do want the hitachi i suggest getting the blue ones at the same time and save yourself the money and combined shipping right then. They arent bad at all but do suck up lube a bit. They are jelly like so they need to be replaced just like other jelly toys as they cant be disinfected being so porous. So just know you will have to buy them more than once depending on how long you use them. But guys do like penetration so they are worth it.
