I think this toy works best as a teaser. It's very simple to manipulate. A little lube at the entry, and just slide inside it. How far you go really depends. You can go as deep as possible, or just wrap it around the head. You can easily hold it in a single hand, and the stimulation works well on every part of you that touches the interior of the toy itself.

The exterior of the toy is smooth, while the interior is very textured by way of ripples. This texture can be overwhelming, even for an advanced user. Someone new to a toy, or very sensitive could find themselves stimulated beyond what they can handle. It's very soft and squishy to the touch. There isn't a smell, though it can acquire one if kept in a confined space.

Overall the design is decent, though I found one thing I consider to be a flaw. That being no hole in the backend. This creates a strong suction, which may appeal to some. But personally, I found it made extra noise that was unnecessary. The size is good in that it is easy to hold in a single hand. I also found the interior wasn't nearly as tight as some masturbators I've come across.

This is a TPE toy. You can use either silicone or water-based lubricants with it. My personal preference is water-based. Cleaning is as simple as using a sink with hot running water, some toy cleaner, and a bit of soap. Since there is only one entry to the interior, you will have to hold it up to allow it to drain back out. Storage is simple enough. You can keep it in a plastic sandwich bag if need be. One thing I've noticed with toys like this, avoid letting it come into contact for lengthy periods with other toys. I have had some items in the past that melted a bit.
