Dear AshMegJo, it couldn't be easier!
We are fully packed with many wonderful options to your liking.
We do have a few wireless options of Hitachi style wands, but I do need some specifications to make a more informed suggestion. For example, do you want it literally to be molded after the Hitachi wand, aka being the same in size, weight, and power? Then I would suggest this
bad boy - it's as close to the original Hitachi as it gets, except it's wireless.
However, if you're leaning towards something less heavy and more agile, my top recommendation would be the magnificent
Magic Force. What it lacks in size it compensates with power and admirable flexibility of the head. Plus it features a lot of fun attachments, which make it the ultimate orgasm-delivery machine.
There is also a massager that is more luxurious than the first two - the poignant
Lyra. It is a wireless wand massager, indeed, but it also has a cool feature of warming up, which, as you might know, aggravates the blood flow and intensifies arousal in our sexy bits.
There are other options we have, smaller or having very specific features. I'm sure you'll be able to find the perfect massage wand on the site.
Best of luck
