Question: Is the stride sufficient for 5'9" (33 inseam) lady?  19 seems short by industry standards.
Document: My machine arrived in a sturdy box and is packaged well. It is heavy and I needed a friend to help me move it into the house. I thought assembly was easy, but I was glad that I first read everyone's complaints about the assembly instructions before I started assembly. It is 2010 and the assembly instructions should include a short DVD video showing how to assemble the machine. The machine is made of high quality materials and operates very smoothly. The 19 inch stride is very comfortable for someone 6 feet tall.
The instruction manual says to turn the machine off after every use and this just seems like a strange place to put the switch. I've only had the machine for a week, but it looks like it is built to last for many years of home use.
This machine is well worth the money. It is very quiet and does not wobble when you use it. The stride length is perfect for my 5'4" frame. The instructions could have been written better, but if you follow them closely and fill in the blanks yourself, you will complete it in about 45 min to an hour- just read ahead a few steps.
My wife is 5'3' and has no problems using the machine and reaching the left and right handrails during use.I think the "short arm" problem is from the left and right handrails being installed incorrectly. Both handrails are marked with a "L" and a "R" on the bottom of the rail next to the mounting holes. They are easy to miss, but they are marked.
I have not had a chance to try the provided heart rate attachment, but the fixed handle grips do have a built in heart rate sensor, and that seems to operate correctly. It has several programs for all levels of elliptical users.In summary, I am very pleased with this elliptical and glad I bought it from Amazon. Make sure you have help when you move it and becareful when you assemble it.
All the screws and washers are clearly separated out, making it easy to follow the instructions and use the right screws. The instructions are short (one page) and the drawing makes it hard to determine where the washers go. But I figured it out without too much trouble. In all it took me about 90 minutes to install. NOTE: Towards the very end I noticed there was a round rubber collar that I had not installed around the mast that hold the control panel.
We have called for days now and nobody picks up the phone . It just says " agents are busy,please stay on the line" and nobody answers ! Shame on them !5stars for the trainer---------------- 0 stars for customer service
We had no problem reaching staff and receiving responses to our emails. The cost of the replacement part was reasonable and my husband was able to install it himself. It runs great now and we use it almost daily.
We contacted Amazon and Diamondback for warranty service. We discovered that there is not an Oklahoma dealer for Diamondback and was not sure if we could get someone to perform a service call. Both Amazon and Diamondback responded to our emails within 24 hours. Diamondback stated they would contact someone to work on the machine. Amazon stated they would replace the machine with a new one, if needed, or provide a refund.
We bought this machine based upon Consumer's Reports review and Amazon's free shipping offer. Being a Amazon Prime customer definitely has it's advantages! Diamondback has one of the easiest set of instructions and packaging I've ever seen in a complicated equipment assembly. This is a very heavy unit to move, so have at least two to three people to help move it in place.It took about 3 hours to assemble and everything worked the first time.
Answer: yes
