Service, Very Useful
First, the service was very good. They gave me details of what I was curious about, and gave me a satisfactory answer. For example, I had asked them to add some features of the software, and they supported and solved it in a few hours. The product has a slim design and there was no inconvenience in wearing it for a long time. It is not only cheaper than other products, but also It can make realistic hand motion in the VR space. And It is very convenient for it has battery which can use for a long time. It was regrettable that the IMU sensor used in the product was sensitive to magnetic fields and was not suitable for working near everyday home appliances such as speakers.
