This is a realistic styled vibe primarily for internal, vaginal use. The tip has the shape of the head of a penis that is just slightly curved to reach your G-spot. It's a little thin, but not so much so that it isn't nicely "filling". The ridges give it a realistic look that, to me, seems like it should be unattractive, but actually might turn you on a little just to look at it, letting fantasies come easier while you imagine what they're going to feel like.

It also feels good rubbed against the clitoris, especially between thrusts, but the vibrations might not be strong enough for some to really get off with just clitoral stimulation.
Anal use might be possible as well, because the base should be just wide enough to not get lost anywhere, but because I'm a little more of a beginner in that area I'm not completely sure about that.

The material itself is smooth and has a strange but nice mixture of velvety and silky going on. It's a little hard to insert without a lubricant, but nice to touch. In my experience, TPR is usually a little more flexible and soft, but this isn't; it's actually pretty firm. It's supposed to be "bendable", but the thickness and material makes it a little too solid to bend more than a few centimeters in any direction.

I've never had a ridged vibe like this, and the "veins" are definitely big enough to feel when inserted; even for someone that isn't very sensitive. It's a fantastically interesting feeling. The shape is just slightly curved to help with G-spot stimulation, but too much, so you'll probably still have to work for it. It's not too thick, which is great for newcomers to this type of vibe, but you still have a full sort of feeling thanks to the ridges.

It's definitely not a discreet toy. A bright purple, veiny penis probably won't make a great mantle-piece when your family drops by.

The Wonder 4 works pretty simply. The controls are just a knob on the bottom of the base, which twists to control speed. It's a steady stream from low to high, and the strength is pretty good for internal use.

My favorite thing to do with it is take my time inserting it, then rubbing the tip of the head against my clit, then it goes back inside and I ride to my heart's content. The vibrations are a little low to bring me to full orgasm just from the inside, but it's still enjoyable anyway.

It's not exactly hard to clean, but the ridges do make it a little difficult. They're thickness means you tend to miss things in the corners, so make sure to be a little extra diligent in rubbing it down with soap and water or cleaner.

Personally, I need really strong vibrations to get off, and this doesn't quite reach that level, but somehow I still enjoyed this vibe. The realistic look helped me get into the mood easier and faster, and and veins and ridges felt nice. I had to use a clitoral vibe to get me over the edge, but using them together was awesome.
