Question: how long is this machine?
Document: This is a nice piece of equipment. However, I must warn those who are just starting out to go slowly. One of us started with too long a workout and ended up with tendonitis of the knee. The physician confirmed that this was the cause, so please don't over-do.
the local company would not sell me this unit at a competitive price, so i bought it from Amazon. putting it together was easy and took less than half an hour. i have had no problems with the unit. it is well made and the best. the parts are highly durable and  you can tell when putting it together it will last a long time.
We've now owned this machine 2 years and have absolutely no regrets.

I used an octane at my gym for several years and purchased this one for my home. It was so easy to put together. I am over 50 an use this machine everyday for an hour. My teen boys take advantage of this machine and love it.
This was a new guideline, but if that was necessary, we liked the machine, and we want to take care of it. Now, we have had the new wheels and tracks a couple of weeks, and I find that after my son exercises (he does sweat a lot), the wheels leave a residue in the tracks. This is not from left over sweat from a previous session; this is not a matter of corrosion, but a matter of the wheels deteriorating while he is exercising!
This is my first elliptical, but I do not think this is a normal requirement. On the basis of what we are experiencing, I cannot recommend the purchase of The Octane Fitness Q35c, and I am highly disappointed in the materials used in this fairly expensive piece of equipment. If I had been told, before purchase, that the machine could not tolerate sweating during exercise, I would have selected an alternative in the market.
It's not obvious, so be sure you remove the protective film after the unit is assembled.The elliptical was delivered by very large professional shipping truck (it's big and 200 lb+ heavy). The driver assisted me which was terrific (be sure to $$ tip well!) And as the other reviewers mentioned, the machine is well packaged and easy to assemble in about 1 hour.Oh and I was able to finance the purchase with an Amazon Store card at 0% (wow!)
We have the Q37ci (slightly upgraded programming and improved handle bars are the main differences) and find these machines to be excellent workouts. Additionally, as others have pointed out, this machine is very low profile so if you have a low ceiling and are tall, you can still use this. Finally, this machine is very low maintenance (keep dust off the rails).We had an issue with the back part of the pedals cracking (my wife likes to use the back part for whatever reason).
I bought this unit (Octane Fitness Q35c) in Feb 2014 (not from Amazon). There are three of us in the family that use it. A 78 year old male, a 76 year old female and a 52 year old male (my son). We all like the way the elliptical works and it is a very smooth machine. However, we have a very disturbing problem that I would never have anticipated from a machine in this price range.
Answer: yes
