Looking at the top 10 products in the sales list of Meiya rowing machines, Sunny occupies 4 seats. There are as many as 27 models to choose from, including the hydraulic SF-RW1205 and SF-RW5639, the magnetoresistive SF-RW5515, and the hydroresistive SF-RW5713 in the US market. However, due to the lack of publicity, Sunny's popularity in China is far less than that of well-known brands such as Concept 2 and WaterRower, and the models currently on sale in China are far less rich and complete than those in foreign markets, and are even stolen by many Chinese brands at the same price.
 
Sunny has seven models of hydraulic rowing machines, with a sturdy frame and track made of aluminum or steel. In terms of rally parts, most models such as SF-RW5639 and SF-RW5727 are double scull-type rowing arms, which are almost like traditional rowing exercises in terms of experience. The SF-RW1205 design is more special, a single steel bar with a hydraulic rod as a cushion is combined with the handle, the feeling of strengthening the abdomen is stronger than that of the arm, although the action is similar to the rope type, but it is slightly stiff, and there is no resilience of silk webbing or chain material.
 
Although the hydraulic rowing machine is lightweight, the 12-speed manual resistance adjustment basically meets the needs of the exercise, and the price is more than 1,000 yuan, but its internal hydraulic oil is not suitable for a high-temperature environment, and the long-term use resistance will decrease, and it is easy to produce noise, and even piston oil leakage. In contrast, the magnetoresistive rowing machine that is also aimed at the low-end market is more worth buying, after all, its magnetron technology uses the magnetic field between the magnet and the iron flywheel to provide resistance, which does not produce mechanical friction, so the noise is less when rowing, relatively quiet, and the resistance adjustment is achieved by manual knob or key electronic control, which is more flexible and convenient. In addition, magnetron technology is mature and often used in sports equipment such as elliptical machines and exercise bikes, with fewer technical failures and safety problems.
 
In Sunny's full line of rowing machine products, there are mostly models that use magnetron technology, with 12 models of magnetoresistive type and 4 models of magnetron wind resistance, with general prices ranging from 1490 to 2800 yuan. Among them, most reluctance rowing machines such as the SF-RW5515 are rope pull type, with 8 levels of resistance adjustment, the steel monorail can be folded for easy placement, and the display of ASUNA 4500 and other models also has a sports program that users can follow along with. The SF-RW5864 and SF-RW5624 are good choices for the realistic feeling of rowing brought by the sculls, and the noise is also well optimized.
 
SF-RW5730, ASUNA 8580 VENTUS and other models are magnetron wind resistance type, in addition to the bellows design in the structure, there is also a built-in magnetron flywheel device, while having wind to provide resistance, and then apply additional magnetic resistance, the resistance adjustment is relatively uniform, there is no sense of frustration, the seat cushion runs smoothly on the aluminum slide rail, and the wind noise is smaller than that of pure wind resistance. However, the function of its monitor is relatively simple, does not support the linkage of intelligent software, and the interactivity is relatively poor.
 
Pure wind resistance and water resistance rowing machines are not Sunny's strong point, and there are fewer models on sale, accounting for two models each. Among them, the RW5623 and other wind-resistant rowing machines priced at 1831 yuan have a strong plastic design of the bellows, and the resistance is adjusted through a brake belt assembly similar to nylon, which is far from the Concept 2 paddle type resistance. The Sunny water-resistance rowing machine takes the people-friendly route, with a price of more than 3,000 yuan, smooth rowing and complete functions. For example, the SF-RW5713 increases the number of impellers in the water tank to 16, and the water flow control is more balanced than the traditional 2 to 3 paddle design, and the whole machine has a built-in personalized workout program and supports wireless heart rate measurement and control function, which has a certain degree of playability. However, in order to control the cost, Sunny subtracted the material of the main frame, and chose a lightweight steel frame monorail structure, which is slightly inferior to the wooden or metal dual-track structure of WaterRower and First Degree Fitness' water-resistant rowing machines.
