I received my rowing machine as expected. It was securely wrapped as everyone said. It was simple to assemble. Took me about an hour because I kept double checking before I put each piece together. I did not find the bolts to attach the computer. I placed Velcro on til I could find some replacement bolts. I contacted the company and they quickly jumped into action to resolve the problem of the missing bolts. Meanwhile my son came over to look at the equipment and see if he had bolts to fit. Velcro was working fine. He then asks, why not use the bolts that are in the computer already? I did not know they were already in the computer. I looked and did not see those instructions. I would not remove bolts unless I know I was supposed to do so.I love the machine. I am using YOUTUBE videos to exercise with this machine. It is sturdy. The seat is comfortable, it is quiet! Quiet is a must- Even when exercising, no matter how hard I push. It remains quiet. I have had the machine about 2 weeks, so if it becomes worn too soon, I will update. It's worth the purchase. Customer services is great to respond. Only by email. No phone number listed.
