ProForm 520 ZN Treadmill

I originally saw this product on Wal-Mart for a bit cheaper, but decided to buy it from Amazon because they offered free shipping, Wal-Mart was charging almost $150 for shipping. Note to Prime customers - they won't deliver it in 2 days. Once I clicked to buy it, it said I could schedule it to be delivered in about 5 days. Shipping was still free, and the 2 men who delivered it were kind enough to slide it down my stairs into my basement (I have an outside basement entrance), which was really pretty great. I didn't have any cash on me at the time to tip them, but I really wish I had! Also, it said it would be delivered between 12:00 noon and 3:00 p.m. - they came to my door at 8:30 a.m. to deliver, so delivery could be any time during the day.Assembly was a challenge, but the directions were very clear. I only wish there were directions on how to get the components out of the box! The whole package is 200-300 pounds, so be prepared for heavy lifting, and you will need help! Once assembled, the unit is rock-solid, even feels more sturdy than the ones they have at my Gym. The speakers have a nice dynamic range, but IMHO they are not loud enough, even at their highest volume setting. The Treadmill folds up nicely, which we will be using to keep our cats from puking on it! It has 2 wheels on the bottom which lets you move it around a little if needed. There is a slot on the top for you to stick your tablet or phone, so you aren't leaning down to watch a show - works great with Netflix! The LCD screen is NOT backlit as advertised, so using it in the dark is not recommended. The audio input works with all electronic devices through a headphone wire - not just iPods (which is great for us Android users).It runs pretty quietly - I expected a much noisier operation, but to my surprise, it's the quietest treadmill I've heard yet. There is a newer 2014 model available through Amazon, but I read in one of its reviews that this model is slightly better and more dependable, and the warranty I think is better. Don't buy this for the 18-pre-programmed workouts - they seem like garbage, and they don't seem very customizable. The calorie counter doesn't take your weight into consideration, so it is not reliable. Where the UI really shines is manual mode. Want to do intervals? just hit a number and it immediately changes to that speed - or incline level.I found it odd that there weren't more reviews on Amazon for this product - check out Wal-Mart's site, there are pretty solid and informative reviews of this model.***UPDATE*** 8 months later:Still working great. The emergency stop mechanism that clips to your belt in case you fall... the clip completely fell apart. I don't really care, I never used this feature anyway. Also, I did notice a noise. The uprights that secure the upper panel to the track are secured by 3 bolts, but these bolts eventually come the tiniest bit loose, and the result is a rattling sound (reminds me of a train on the railroad). It doesn't feel loose at all, but if I tighten it, the sound does go away. Then it's usually back in a few weeks. Not a real problem, just a little annoying. Still works great, and I am still enjoying this machine. Since originally writing this review, the price has gone up by 30%. I wouldn't consider this a great buy at this time.

Piece of crap the tread belt runs at different speeds every time ur on it so you need to up the speed. only one speaker works and its hard to see the read out, also the heart monitor is a joke it bounces around but don't call an ambulance when ur heart rate goes over 200. I constantly tried to contact customer service but no response just a repair ticket was issued. SAVE YOUR MONEY!!!!!! DONT WASTE IT ON THIS TREAD MILL

I would give 5 star if the display could be read. Can't tell how fast you're going or how high the Incline, calorie burn, nothing.

Overall, the unit has met my expectations to date. Assembly was straight forward, unit has operated well for the one month of service it has seen. One area that is not as good as expected is the display seems to be too dim and the heart rate monitor is suspect. All in all, so far so good.

Great treadmill great experience with Amazon

Working great so far!
