I would say the best use for this is not completely by itself. Feel free to use it while doing other things or pair it up with something else, but while nice, this toy isn't meant to completely fill you up all by itself. Instead, it makes for a nice addition to anything your brain can think of. It's small enough to make it inconspicuous. A nice metal build should be safe with any lube and not dangerous.

The metal, along with the pink jewel on this, is very nice. Reactive to the temperature, so it may be a little cold if in a cold room. But it should last a long time and be easy to wash. Although it is very small and best for beginners, the metal makes it feel more filling than the softer material.

A very classic design, so nothing can go wrong here. The egg-like shape makes it easy to insert. The neck is very small so that it can stay for a long time and not slip in or out. The flared base is nice enough so that it is safe.

Although it is meant to be small and meant for beginners, I do feel like most people will feel the need to upgrade very quickly, so keep that in mind. Besides that, the performance is good and how you would expect it. No electronic parts that could go wrong, so there is nothing to worry about there.

A nice addition to this is a very small carry-on pouch, making it very easy to keep clean and store it anywhere and carry it as you please. It is metal, so it should be very easy to clean with water and soap, and any lube that you like should be compatible.

The only thing I could say here is I wish the shipping package was smaller, so all that material and space was not wasted in transporting this. But the toy itself has a pouch, making it very easy to store.
