  • Darn Good so far

    Machine was so much bigger than expected, but this is a good thing because it is sturdy. Doesn't have all your bells and whistles like inputting your weight or built in fans but I didn't need those. I love the one touch speed and incline buttons. Easy to operate, works well, even at maximum speed. Excellent speakers. I use mine for walking so suits my purpose, but could be used if you are a pro-runner. Overall excellent purchase for the price!!!

    • How accurate was the sizing? Much bigger and heavier than expected
    • Please tell us about the quality of the product. There was a couple of small parts that didn't fit, but everything else works well
    • Was the product free of any manufacturer defects? Yes

  • 1st Treadmill Purchase

    Firstly, I'm please with the shipment of the treadmill. I was called to arrange a delivery time, and the person I spoke to was really helpful with getting me a timeslot that worked with my schedule. Also, the driver called me to let me know that he was on his way. The box arrived free of dents or rips; it looked untampered with. The only thing is that one of the sides of the base has the plastic misaligned, like it had popped out. I was worried, but then I pushed it together really hard and quickly and it snapped back into place. The treadmill looks quite good quality and feels sturdy. Good points... 1) The base lifts up for storage 2) The wheels make it easier to move the treadmill 3) You can hook up your mp3 player to it and the treadmill acts like a speaker 4) The heart rate monitor 5) You can see the shape of a track and where you are on it, an overview, to gauge where you'd be if you were on a real-life track. 6) The handle bars are short so that you can easily move on and off the treadmill from the sides, even put it closer to a back wall without worrying about getting on/off the treadmill from the back only. 7) The cost on Overstock is 1/2 as much (at least) than on the manufacturer's website. 8) Free shipping with Overstock, a ~$50 savings. Bad points... 1) It's really noisy 2) It doesn't power off on it's own; you have to flip the power switch (at the very front bottom) when you're done. 3) The big plastic grey rounded-trapezoid pieces/caps (at the base of the front frame) aren't secured in place (more of a cosmetic thing when you move it or maybe if you knock into it, they might lift). 4) It took me 3.5 hours to put together. 5) It's bulky to wheel/move Notes... 1) You will definitely need another person's help. I needed help 4 times 2) Although there are wheels, it takes some momentum to swing the treadmill back in order to wheel it

    • How accurate was the sizing? Accurate
    • Please tell us about the quality of the product. Really Good
    • Was the product free of any manufacturer defects? Yes
  • Great value,

    The treadmill was delivered very fast, within two weeks. It was easy to assemble. Just mark and number a paper. Circle the screws and nuts, so you can grab them when the directions call for them. Two people can do it in 1 1/2 hours. My twelve year old son and I did it. Make sure you assemble it where you are going to be using it. Once it's together you will not be able to move it.

  • great treadmill

    I love this treadmill, other than putting it together, it is great!!! Its quiet and can run on it and not feel like it is unstable! highly recommend

    • Please tell us about the quality of the product. very well made
    • Was the product free of any manufacturer defects? yes
  • Good way to exercise!

    Delivery takes quite a few weeks but delivery company is very good with following up and scheduling based upon your availability.

    • How accurate was the sizing? very accurate
    • Please tell us about the quality of the product. Quality is good
    • Was the product free of any manufacturer defects? It is indeed difficult for one person to put together. It is heavy too. Also, check parts as I was given two left arms that go on each side of the console. I called the company and they were very good about sending a replacement. However, that took 10 days, which I was not happy about waiting.

  • Works, but you get what you pay for

    The treadmill works, although the freight shipping is slow. It took a while to assemble, but it does work. This is a very basic and cheaply made treadmill, exactly what you can get with this price. Can do the basics, but the quality is not comparable to what you can get from a professional gym. I use it gentlly, Willl see how long it lasts before stop working.

  • Very Dissatisfied Customer

    I order the Proform 505 Model 60910 with built-in iFit and Google Maps because I wanted my workout sessions to be fun and adventurous. Unfortunately, after waiting nearly 4 weeks, I received the Proform 505 Model 60913 which has a basic console without the iFit and Google Maps technology. Although the machine functions properly, the workout time is boring and my whole purpose and intention to make exercise more interesting and challenging to look forward to, has become, due to its limited capacity, merely a dreaded routine. I didn't want to wait another month to receive the model I ordered so I kept this model with much dissatisfaction and disappointment due to's monumental mistake!.

  • works great

    it was easier to put together than some of the other reviews mentioned, but the box is very heavy. it is easy to personalized your program, but i still tend just to program speed and time. i do not think it is any less noisy than other treadmills i have used. all in all i think it was a good price for the product.

  • Looks good - Shipping bad

    I was excited to order the product for the wife and I as a Christmas gift to ourselves. It arrived 3-4 weeks later. However, it had numerous obviously broken parts which we could see once we unboxed it but before any assembly. We called in and they sent us replacements which arrived in about a week and a half. The assembly went fine but then we noticed one of the rubber feet was broken. So to prevent any stability issues I called in again today for a replacement for that final part. The gentleman from the company tried to sell me an extended warranty, put me on hold for 10 minutes and then I received an e-mail stating a completely different part had been ordered. So I called back again to get the right part sent which should hopefully show up in a week or two from now. At that point I hope the machine is as fun to run on as it looks!

  • Everything it says and more !!

    This product is everything it claims to be. the quality is excellent. I love that you don't need to be a fitness guru to enjoy and use this proform. It's very user friendly with easy assembly. Most of all i love that has brought this product to us at such a remarkable unbeatable price! This is a must have for everyone.

how much voltage does it take none12345697 on Jan 4, 2013
Subscribe to Answers
Answer This Question

The treadmill brands including ProForm require a 120-volt circuit. A standard residential outlet in the U.S. is 120 volts. However, the actual voltage is typically between 117 and 124 volts. In general, a product rated for a 110-, 115- or 120-volt circuit is compatible with a standard residential 120-volt outlet. overstockcustomercare1 on Jan 4, 2013

What is the difference between a ProForm 400c and this treadmill? drgjones on Dec 29, 2012
Subscribe to Answers
Answer This Question

There is little to no difference in specs on these treadmills. They have the same size motor, tread belt, and weight capacity. The 400c has 3 extra built in workout apps and is a model year newer, but as far as performance there is not an advantage to one or the other. overstockcustomercare1 on Dec 31, 2012
