There are increasing production plants in various industries in China. Let's talk about the test box industry. At present, there are many problems in the test box industry. The following author writes some to discuss with you.

There is competition in the price of the test box in almost every industry, but the test box industry is quite fierce, and the price of the popular product is the lowest in less than a year. Bad competition, we often get rebates, and some purchases are very outrageous and the rebates taken are several compensations for the original ex-factory price. If the buyer ’s senior executive fixes the price, the buyer will desperately press the factory price. The more rebates you get, the more manufacturers only have to compress manufacturing costs in order to make money. The cost is low and the quality cannot be guaranteed. The equipment has frequently failed in less than a year or two. Not just users and manufacturers.

There is also natural competition in the market, and the price is basically minimized in the country with low technical content. The product quality has not been improved. The author has been engaged in test box equipment for more than ten years, and some products are like this for ten years. There is not even worse.
