Question: How-come this is 2014 model when there are reviews posted all the way back from March 2011?
Document: All the information you need is in the reviews. I have complaints about the heart monitor (worthless) but there is enough good to make up for it. This is an excellent valued treadmill and will be in our family for years to come. My wife has used it 4x/week and it's performed great. Would buy again in a heartbeat.
I paid less than $600 for this treadmill and you really cannot beat that for what you get. The treadmill comes with many of the features you will find on a treadmill in a professional gym. Additionally the extra width compared to other non-commercial treadmills is a must have for any serious runner. This model is very solid and for the most part fairly quiet. You will read reviews that say otherwise but you have to understand that all treadmills are relatively noisy.
I did not buy this treadmill through Amazon, but wanted to share my experience with this treadmill. First of all, it weighs a lot...thankfully the delivery driver helped me get it into my place. Most reviews say not to try putting it together and mine did come with an 800# to have a service tech put it together. Some reviews said it needs 2 people to put it together.
This is all without the i-fit module which I have not purchased. It also folds up pretty easily and almost lowers itself, which is a relief for anyone like me with back issues. It took me and my dad three hours to put it together, and it was complicated. I recommend getting a professional to come put it together for you if there is one in the area. The manuel is confusing and the construction a little counterintuitive.
So I called Amazon and let me say that Amazon is super great about handing customer issues. I really couldn't be happier with them. They arranged to take back the item no problems at all. So a few days later the broken treadmill was picked-up and I was fully refunded a few days afterwards. As far as the ProForm 505 brand and model, I can't give a review on how well it worked, since it was broken on arrival. All I can really complain about is their terrible packaging.
Had my doubts with the reviews. But I just got mine, and I have to say - it's baaaddddaaazzzzz (in a good way). Slapped it together in 2hrs from opening the box to testing it (I'm the girliest girl in the wirld). If you were expecting to practice your mechanical engineering degree - you should consider getting another. This was all screws and the obvious fitting pieces.Runs like a dream.
As a sidebar you should prepare yourself to be on hold for at least 20 minutes every time you call Proforms customer service hotline. Back on point I called Proform and was told sure the motor is covered but you have to pay $140 to have their guy come out and confirm that is the problem. I agreed to pay the service fee and waited for the technician to call and setup an appointment. I continued to wait for an entire week.
The longer and wider tread belt is very nice. The features are more than ample. I do a lot of running and racing so I spend a lot of time on a treadmill training, I have to say this treadmill does not wear on my knees and back the way others have. I am very pleased and I love the speakers to listen to my music! Definitely worth the purchase!
Several times they told me they would give me a call back with a better status and never did. On the day the treadmill actually came, I did not get any phone calls until the driver was 30 minutes out. Luckily, my wife was at home to receive the delivery, but it was in the middle of the day. No one from the company called me to tell me my treadmill was on the way or that it was now at the correct distribution center.
They sent a new motor, new cushions, a new control module and new cables and set up an appointment for a technician to come install everything, all under warranty.Everything was installed and taken for a test spin with the technician here. Unfortunately, the display and motor stopped working properly on the next long run a few days later. I called Proform back and they were again very pleasant and helpful, but wanted to send another motor and now replace the main console as well.
