Swelldom is a brand under the name of Hangzhou Black Panther Sporting Goods Company, founded in 2011, specializing in small and medium-sized fitness equipment. Although it is a relatively young sports equipment brand, Swelldom has a very diverse product layout in grip devices, covering A-type grip devices, adjustable grip devices, grip rings, finger strengths, etc., and the cost performance is also very good.
 
SWLB-009, HB-0012, and DZJS-001 are all adjustable grip strengths, which can be appropriately tightened or relaxed within the preset range to achieve the change of grip strength. SWLB-009 is an improvement on the basis of the ordinary A-type grip device, and its principle is the same as that of Xinyi Wanjia's U-shaped grip device, which can adjust the position of the handle to achieve the effect of force change, and its adjustable range is 50-150 pounds. Compared with Xinyi Wanjia's U-shaped grip device, SWLB-009 has a lower strength level, which is more suitable for entry-level exercisers, and the price is 28 yuan, which is cost-effective.
 
HB-0012, as a relatively popular R-type grip device in the domestic market, is more cost-effective. In fact, there is no strict distinction between R-type grip devices on the market, and they are generally included in the A-type grip device, but compared with the A-type grip device, the R-type grip device is not only more like an "R" in appearance, but also the most important thing is that it is an adjustable grip device, and the strength level of the general A-type grip device is fixed. Compared with foreign grip devices, domestic grip devices generally use kg as a unit of measurement, while HB-0012 has a wide range of adjustable coverage, from 5 to 60kg, and the price is more affordable than other brands, only 15 yuan.
 
Although SWLB-009 and HB-0012 are very good, Swelldom's leading product is DZJS-001, which is also an R-shaped grip device, its special feature is the automatic electronic counting function, which intuitively presents the user's exercise data through the LCD screen, which is a rare "smart" grip device on the market, with an adjustment range of 5-60kg, to meet the strength needs of general exercisers, and the price is 56 yuan.
