Founded in 1979 by Taiwan's "luggage king" Xie Mingzhen, AirMaster has a total of more than 5,000 employees in three factories across the Taiwan Strait, with an annual output of 6 million suitcases, 90% of which are exported to developed countries such as Europe, the United States and Japan. AirMaster is the first merchant in Asia to pass the ISO 9001:2008 international quality certification, and has won the TAITRA Excellent Product Design Award for many times.
 
AirMaster uses German Bayer PC material to make the suitcase, and the multi-layer composite structure enhances the impact resistance of the box. Thickened aluminum alloy tie rods, silent universal wheels and TSA customs locks are also the basic equipment of the PC box. Among them, 9C5 is the "79 years commemorative model" launched by AirMaster, which is different from the general hard case, 9C5 has an aluminum alloy middle frame, which is safer than the zipper, but this move also increases the weight of the box, the net weight of the 19-inch cabin suitcase is 4.2 kg, ranking last among all the brands on the list of PC hard cases. The lever has only two adjustments, which is not friendly to tall users.
 
The Gold series is a high-end product line of AirMaster, such as the 9P0 suitcase, the aluminum alloy narrow bezel and the double built-in TSA customs lock greatly improve the security, and the service life is much higher than the ordinary zipper lock. Unfortunately, this case is still unsatisfactory in terms of weight, the net weight of the 20-inch cabin suitcase is 3.4 kg, and the net weight of some styles such as the 9L6 cabin suitcase is even as high as 4.2kg, which is close to the pure aluminum-magnesium alloy box, which is at the lower middle level in the PC hard case.
 
Although the performance of Yashi in the weight and detail design of the box is relatively inferior, but the victory is in the number of products, and the price advantage is obvious, except for the Gold series of products The price is about 1000-1500 yuan, and the rest of the hard box price is mostly concentrated in 500-1000 yuan, which is suitable for people with a relatively limited budget.
