Thrilled with my purchase. Like other reviewers, it came down to this make and model or the Sole f80. i did a lot (A LOT) of research between the two and finally decided on the Smooth. What sold me was the warranty, the Runners World Recommendation, the countless other positive reviews for this machine and all of their models, and the price. i really didn't want to spend over $1000 for a treadmill, but I didn't want a treadmill i would have to replace in 5 years either. the longer running belt is a perk, wasn't used to all the space at first but now i can kind of spread out without worry of slipping too far back. the speakers are alright, they're decent enough. Fan is of good speed, controls for incline and speed respond quickly, screen is big and easy to read. Very basic screen which is perfect for me. Comes with heart rate sensor, which my husband uses and likes because he can make a custom workout based on heart rate. I havent used any of the preset programs, i like to fiddle with the speed and inclines on my own right now, but i am looking forward to trying them out in the future. very sturdy machine, hardly any bounce or movement at all, even when my 6 foot 200 pound husband is hoofing it on 7.5. Really absorbs the impact. I have run on incline of 10 and performed great. Husband put it together himself in about hour, taking his time. Instructions were straight forward and easy to follow. need 2 people to move it at delivery time, but quite manageable to put together by oneself once in place. I think what sold me on this machine was reading that, if one is a serious runner (or strives to be), not to purchase a treadmill because of the bells and whistles but on the solidness of the machine itself.Read more ›

I got a lemon right out of the box. I got the same speed errors that Pausanius had on his 7.35 model. Paying for it brand new, I called Smooth asking for a replacement. No matter how hard I tried, they refused and eventually agreed to send out a technician. Two weeks later, a Smooth technician showed up and said he would order a new motherboard. No part arrived after a month. I sent them several emails and BCC'ed myself for future references, no email reponse from Smooth! I called and was put on hold for 30 minutes. Eventually, a support guy answered the phone. He said there was a mistake so he had to reorder the part (???) after putting me on hold several more times. The part finally arrived after another two weeks and a Smooth technician came to install it. The speed errors are gone but the belt now squeaks and skips anytime I run over 5.0 mph. It squeaks so bad that it feels like the whole running deck is falling apart. I wish I had bought the treadmill at some store so now I could drop the "300 lb lemon" right in front of the store.

Verified Purchase
Revieved shipment at 4:30 PM, was running by 5:45!!!!
I was able to assemble this with the "disposable" tools included...didnt even have to open my toolbox. Quite literally 4 bolts, 4 screws and clipping a few wire harnesses together. The only challenging part was moving the unit into place, as the freight guys would only bring it in uust inside my door. I suggest two people to move it. Very doable!!! Runs like a dream. Unit is very quiet as the name implies, quite smooth. Programs are cool.... Very straight forward operation. I am quite pleased. If you are not tech/tool savvy, take your time and make sure all wire harnesses are connected to their proper mates. The directions are very easy. MANY of the screws listed on the parts list are already on the machine and in place, so dont freak out because they're not in the bag! Thats all I can think of. OH, this unit is recommended by Runner's World mag, and it is a goooood recommendation!

OK now it's 2015 and the read ill is dead. Mother board burned out rendering it useless. 4 years of constant use may be the life of these things, I don't know. Thought it would last longer.

The Smooth 6.75 is a decent treadmill. It has a strong motor, easy setup and fairly easy to use interface. My biggest disappointment is that 1) does not have 1 touch speed settings above 6 mph nor does it have it below 3 mph. 2) You can not set the speed prior to engaging the motor and 3 sec countdown. 3) incline and fan does not reset after hitting the reset button. 4) Running bed is a bit stiff and the belt is shedding for some reason (not sure if it is rubbing up against something). and 5) Chest strap heart rate monitor is not accurate. It often says my starting pulse is 120+ beats vs the hand grip pulse 65 beats.

DO NOT BUY FROM THIS COMPANY  ONLINE.. They will take Your cyber monday and holiday money and you will not get your gift in time for the holidays, you will not get good customer service, most will regrets this purchase. Spend your monies with a company that has a better reputation and appreciation for your business.  No need to take my word for it (although my painful ongoing saga is outlined in detail below) ...just be diligent and research online reviews for smooth fitness and you will see sporadic but corroborating reviews of others  who have had similar experiences with Smooth Fitness.  If you happen to be lucky and not be one of their victims then great but given the demand during the holidays coupled with their disjointed operations, I suspect your chances are high of having a horror story to share (like mine) will be a increased. Dont take my word.... Just  research it. Type bad reviews smooth fitness and you will see I am not the only victim.... You have been warned. The product may receive high ratings from treadmill websites etc and the product may be ok but if you ever have to rely on this company to get the tteadmill delivered, honor their warranty, provide the assembly service (you paid for) of anything else hat is customer service related.... Grab the aspirin and get ready for the headache snd runaround of your life. Other customer friendly treadmill providers are more worthy of your business.. Do yourself a favor and pass on this one. The product I cant speak on, as I am still yet to bet mine 43 days later but their service I can speak on..... They are horrible and to be avoided  at all cost. After spending this much money, ask yourself if it's worth the headache......Read more ›
