Query: DON"T BUY THIS URELIABLE PRODUCT

I bought this rower new 8 months ago and typically use it 4 times a week for 30 minutes. So far, it's gone through 4 pairs of failed shocks. Some leaked hydraulic oil and eventually their lost resistance and some just lost their resistance without leaking. Some took up to 3 months to fail and a couple of them failed immediately right out of the box.Initially Stamina was pretty good about replacing them but now when I call, since it's out of warranty, I'm essentially told to go pound sand. During one of my calls their customer service reps actually told me that "it's not meant to be used every day". I find this just unbelievable! I would rate it at zero stars if that were possible.BTW - back in the '80s I had a Precor 612 that I used regularly for years and it never had an issue with the shocks.
