Both Firstdegree and WaterRower rely on their own pull to adjust the resistance, but Firstdegree has a resistance adjustment button, which can adjust the greater resistance, which is more convenient. If the paddler wants to adjust the resistance more, he needs to add water. WaterRower looks better and looks better at home. On brand recognition, that is, WaterRower will be greater than Firstdegree, and the card house owner will use WaterRower. But WaterRower will also be more expensive.
These are advantages and disadvantages. Think for yourself. But I advise you not to buy domestic products. Don't buy some apps just because they have them. The most important thing for us to buy rowing machines is to exercise, right? It's not like buying an app. Although some brands claim to be "smart" and have apps, you can see that their water tanks are still locked with screws ... you will know that there are lower ones.
