The Hitachi can be used for everything from back massages to clitoral stimulation. Given the plethora of available attachments, it can be used for G spot orgasm,s and also as a toy for men (there is a sleeve attachment that one can buy).

This is a plastic base with the head being of a softer material. The neck is not super flexible but does give under pressure.

I wouldn't say this toy is discreet by any means. It's large and loud. However, it is portable and fits easily under a bed or in a dresser drawer. I don't think the size has any impact on novice versus advanced use although the vibration may be a bit powerful for some.

It has three settings. Low (haha), HIGH, and off. The vibrations come from the head which is on a semi-flexible neck. The toy is noisy, and there is no mistaking it for anything other than what it is. It's not waterproof and is a plug in so it would simply not be a good idea to even attempt using this toy near water. It makes up for its limitations by its power. This is my go to toy in my collection, and I absolutely LOVE this toy. It's easy to use and effective.

It's easy to care for. I keep it under my bed for the most part where it's easy to reach should the need arise. If it needs to be cleaned antibacterial hand soap and water is effective. It can be used in coordination with dildos and other toys. I've only ever used water based lube with it as that's typically best for most toys.

It came in a rather simple cardboard box and is fairly straight forward: you plug it in and flip the switch to one of the two settings.

This is by far my favorite vibrator. I tend to burn through vibrators, and this one has lasted almost ten years and is just now starting to show it's age. I can't stress enough how great this toy is. I tend to struggle with climaxing, and this can almost always get me off and does so rather quickly.
