Honey, rowing boats with hundreds of dollars are basically not easy to use. From the design point of view, it is generally mechanical jitter. From the material point of view, a few hundred dollars is not enough to support the durability, comfort and safety of that structure. If you only want to spend a few hundred dollars on fitness equipment, consider other products.

If you really like boating. Then I suggest parents spend more money to buy a brand of rowing machine, which is magnetically controlled and silent. First, the product quality itself is reliable, second, there are professional after-sales maintenance services, and third, there are scientific fitness methods.

I use Donatelli's monorail magnetic control system myself. For reference only.
