If you have questions about specific products, you should try checking out the reviews first before bringing it to the forum. Sometimes certain products don't have reviews but the PicoBong Ako actually has 6 reviews on it which you can find here: link
I don't own this product but 3 of the 6 reviews gave the product a 5 out of 5 rating and the other three gave a 4 out of 5 rating. Those are pretty good ratings so I would assume it's worth it.
My favorite toy!!! Worth every penny. It is silky soft to touch. I love to use it during foreplay with my husband. Once I reach my first orgasm, he jumps into the action and it allows waves and waves of pleasure. Since I had a complete hysterectomy, vaginal orgasms are not possible anymore (cause I don't have one)......so focusing on clitoral orgasms still brings me great delight in personal play time and husband play time. I HIGHLY recommend this toy. I have used cheaper bullets in the past, and they always die, especially the ones that have a wired remote control. The Ako is self contained fun and easy to adjust with the three slightly raised control buttons. GO FOR IT......especially good for somebody new to toy-play.
I think its worth the price. I usually go for high powered plug in the wall vibrators/massagers like the Hitachi and the Wahl. That being said...I was so happy with this that I used it to the point where its dead and in need of replacement. And I have no qualms about buying another one. So....
