Question about Hammer Fitness Pro Force

Used for 4 months almost every other day, and the last two month always at full load because I gained fitness and level 16 became too easy for me. The rewinding mechanism broke today and I opened a guaranty case. In summary, if you search a rowing machine to be used to gain fitness, and you are already a large and fit person (I was a long distance runner), then this machine might be too weak for you.

No comment, see previous answer.

Have you only been using the device for 3 weeks?
So we can't judge either.
It makes a good impression so far!
