Very pleased. Easily assembled, quiet, folds for transport with minimal effort, functions perfectly.

Five stars. Arrived within 2 days of ordering.Cheaper on Sunny website than on Amazon. Saw this (in pink) on a YouTube “Best Treadmills of 2020” video. I was on the fence between this, a Nordictrack and a compact treadmill by Horizon. The chic, clean and compact design of this treadmill beat the others despite not having a fancy screen to stream classes and such which I find unnecessary anyway since I have a phone, iPad and Tv which can easily suit that function should I desire it. The lack of big **** control panel is actually what makes this machine look great in any space. But the beauty of this treadmill is the cherry on top of what has been an amazing experience so far. I’ve run on it for an hour every day since ordering it two weeks ago and it is always a fantastic workout. I’m ecstatic to be running again since the gyms have all been closed and I dislike running outdoors. This treadmill delivers everything I expect of the treadmills at a gym except it’s not as huge and obtrusive. I absolutely love having my own treadmill in my own space. I feel like this treadmill was designed just for me... that’s how well it suits my needs and how positively it has affected my physical well being in a short time. It’s super heavy... I got it up the stairs to my place alone but it was a horrible struggle (Literal blood sweat and tears) and I would not advise it. Get help. Don’t do it alone. But other than that, assembly was simple... five minutes max. It made a strange noise when I first started using it but I had it on a flimsy mat on carpet and you’re not supposed to stand on the belt when starting or stopping the machine soooo... after placing it on Traffic master interlocking rubber tiles and following the instructions I haven’t heard the scary sound again. My only complaint is that the instruction manual is rustic and isn’t helpful in getting quick clear directions... very confusing because everything else about the product is presented so well... a better instruction booklet would make assembly and getting to know the machine easier and faster. Best purchase of the year for me. Can do my cardio at home now even when gyms reopen.

I have bought this compact treadmill for my wife. It is a birthday gift. She loved it. The Spaceflex is perfect, wide running deck, pretty quiet, nice design, beautiful display and connect your cellular to built-in speakers, playing your Spotify selected musics. But, I really appreciated how fast the Sunny team answer your emails or online questions. I also received the Spaceflex faster than I expected. Excellent experience!

Absolutely a gem. Quiet operation, very compact and easy to use. Love the contemporary design. Big treadmill features but with a small footprint!

This came unscathed but damaged box.. easy to set up and oil ..I like the leveling adjustment for floor stability .. The folding and size of it are why we purchased.. but so far well made, it seems, and hands down our best investment for our health.. I’m 5’4 150lbs and my husband is 5’11 200 and works great for us !

The treadmill is inclined out of box. Clearly, if you like to run uphill , it will be to your liking. Otherwise, be aware. I am a two miles daily runner, but uphill running hurts my knee.
