I would say this could be good for a beginner toy. The variety of vibrations would allow them to learn what they like and don't like, though seasoned veterans can also enjoy this toy. Anyone could enjoy this.
The design is very simple. It is a curved G-spot bullet that is connected to a control box. The cord can be used to retrieve the bullet, though I would not suggest using this for anal play. I personally would not trust the cord if I needed to pull on it much, and without a flared base it could get lost. Personally I would like the bullet to be longer, because as it is, the bullet is not long enough to reach my G-spot. The curve is good, it seems to be at the right angle, but it is hard for me to say since I can't use it for its intended purpose.
I found it to be a comfortable size in width, , it's not too big but it's not too small. I would say this is a medium sized bullet. This would be a good size for most users including beginners. Though for individuals who like queen size toys, I would suggest looking elsewhere. I think this would be too small for you.
The toy itself is not very discreet looking in my opinion. It's a medium sized curved bullet with a neon green cord attached to a control box, which is also bright green and purple. The colors alone make this toy stand out.
