This one is great for beginners, it's my second anal toy.

The posh O probe can be used anally, or vaginally. Just be sure to clean it properly before going back and forth. You can use the O probe for solo play or for couples excitement. The curve can lend to g-spot and p-spot stimulation.

It is waterproof, has multiple settings and it is made from a body safe material.
It's made of silicone, which is the best material for sex toys. It also rates a 10 on the Eden safety scale. You can wash it very easily and many ways; with soap and water, toy cleaner, boiling it, or throwing it in your dishwasher! This is one of the best toys I have ever had.
Since it's silicone, you should really use water based lube so you don't ruin it. Storing is very easy, I keep mine in the baggy it came in and hidden in a drawer.

I love the ring on the end it makes it very easy to hold onto, easy to use, and maneuver. The bullet comes out really easy if you want it to and can be replaced. It runs on a AAA battery which is really nice! The bullet has three settings: low, medium and high. You control the bullet by pushing the button on the end. The bullet is made from plastic and rates an 8 on the Eden safety scale. You can clean up the bullet with antibacterial soap and water or you can use your toy sprays or wipes.

I was very satisfied by the vibrations, especially on high. It's not very loud and can't be heard through a door or if you're under the covers. Since the bullet is removable it is easy to place a stronger bullet in the probe.

The silicone gives just enough and will bend if you want it to, also it stays in place when you put it there; I love that! It comes in a large brown shipping box completely discreet no one knew what was inside and inside the actual box is a small plastic bag containing your toy! I tossed the packaging and small box, keeping the bag to store the toy in.

I am still loving this powerful little toy. I don't use it every time, but when I do, I love it!
