Hmm, for ten bucks, you could give it a shot. Not a huge loss to you, even if it didn't work out for you in the end. 4 vrooms, 2 bees, and you can use it to search for your g-spot. If you are someone who is tight or just enjoys a slim vibrator, this is definitely not intimidating. Hard to not pass it up!
...Although, do take into consideration that while it's a non porous material thus high in safety, it is made of plastic which is hard and inflexible, but still smooth. However, the firmer material may be what you want to effectively hit your g-spot with as well.
But if you think the firmer material may actually hurt you when you enter it in or may have some drag, you may want to consider another more flexible material like TPR silicone. While it is porous, it does allow for more gentle entry and conformity to your body.
So, really, it's up to you if you think you'll need a firmer texture to hit your g-spot, or if you want something more conforming and flexible. I'd say, given the price, you could still buy and see if this material combined with the features and slim girth of the toy is what you find enjoyable or not.
