This product has excellent compatibility and usability.
It is the perfect size when using a 65mm hole from another manufacturer.
It seems that it can be used up to a maximum hole size of 70mm.
Shanghai Dong can go up to 12cm, which is very good.
I also bought a product with a height of 7cm and tried it, but the irritation was minimal.
I kept falling out of it, which was quite inconvenient.
This 12cm product has better stimulation and is more comfortable to use.
The buttons are intuitive, making height and speed adjustments easy.
The only downside is that the exercise is simply repetitive without any variation.
Rather, it was convenient because you only needed to worry about the height and speed without having to worry about the mode.
It can be fixed to the monitor arm and used hands-free, making it convenient to use.
