It’s (as of my knowledge) the only one of its kind on the market. The plasma ball is a lot of fun to mess with, and for the price of a Plasma Ball Light you could get from the mall, you can have one that brings you a whole other kind of pleasure.
It’s definitely something I’m keeping in my toy rotation.
Personally, I love my Lush. It’s one that stays in my bedside drawer, along with a few other choice toys. It’s versatile, and the low noise makes it great for getting into naughty fun at not so naughty times. The lack of clitoral stimulation, paired with the price stops me from giving it a higher review.
Is it worth the money? When it’s on sale, absolutely.
I absolutely recommend getting one. If you’ve ever thought about adding something a little more quirky to your collection. The bumps and ridges are noticeable enough for this to be something that none of my other current toys can provide, the suction cup is actually decent, AND it’s strap-on harness compatible!
