It's been 25 years... tidy up, thank you very much for your help! I hope everything goes well in the new year!

This product is a niche industry. At present, other first-line brands in the same industry are still lifting and lowering a single touch screen. A computer input device relies on raising its hand all the time to touch. It is tiring to think about it. It is estimated that this mode will be eliminated. At present, the business of this product is not bad. It is predicted that this industry will be such a form of product in the future!
