The simulator is a professional tool that have to be handled with care. It is not an "antistress" tool or a toy.
The simulator can resist hundreds of presures. However if the product is forced or receive lots and lots of pressures in a few time, there is a possibility that the ball could break and leak. But making a "normal use" the ball should resist months and years.
After a misuse or a long term use the ball can be wear out, so the simulator can be repaired by substitution of the ball.
The simulator can be cleaned with water and soap. The jelly inside the simulator is non toxic and washable.
The ball can be introduced by posterolateral part of simulator. Firstly you should wet the cords and the ball.
You can see the method of substitution in this video:
You can fill water in the ball with a syringe and a fine needle.
