I have attached a video review and am reviewing this in length, so go get a coffee and your reading glasses.
** FYI, this review is for walkers only.
I was very impressed by this walking pad. It's REALLY quiet! Right out of the box plug and play. The remote has a mute button for muting the beep of the countdown as well as speed increases and decreases. I suggest you don't use it. It keeps your attention on the machine. It has a manual incline so you will have to raise it before you use it. I prefer manual as there are less things to go wrong and repair. Overall, after the days long researching I've done and narrowed down to three pads, I can say that this one DESERVES the 4.5+ rating it has. This was about mid-price of the three I narrowed down to, and even though the $199 one was rated as "customers keep this item", I was leary because it had more 1 star reveiws than this one which had one at the time I was researching. I found many of the one star reviews had to do with physical shipping damage, so read them carefully and make your own decision.
This is why I chose this walking pad: I've read reviews on about 17 other pads I was researching that say 15 inches is not enough width to walk. It's not if you're a giant. My son is 5'11", 175 lbs and he has a half stride of 25 inches when walking, and he had lots of foot rom at the top and bottom of the pad while in motion, so it would seem good for someone up to 6 feet for walking depending on their stride.
The width and length of the physical machine itself is 19 x 45.25 inches. The belt is 15 x 39 inches, so the portion you're actually walking on.
To determine the width of the walking area you will need, you need to figure out your half stride. A full stride is when one foot, say, your left has gone from front, to back, to front again, which is your full stride. You want HALF of that. First, walk around the room until you have reached your comfortable stride then STOP just as you're about to lift your opposite foot which is bent so that one foot is bent and resting on the ball which is the round bone just below the big toe. Have someone measure from the top of your flat foot to where the other foot rests on the ball. That is your half stride. Mine was 23 inches. Next, measure the WIDTH of your stride. My width was 13 inches stopped and 11 walking. So, fifteen inches was more than enough for me and I'm average height at 5' 5.5". Remember, when you walk, your feet move toward each other a bit, not out wide like a duck.
Do NOT beleive the pictures of the super tiny AI models in a RUN stride. Their stride is abnormally abnormal.
The M and P is the Mode and Program. I'm not a jogger, so these are not important for me.
Carefully open the box, unpack and inspect everything. Turn it on to ensure no error codes are present. Make sure you have the manual and SEALED allen key and silicone oil, spare battery for remote and the remote as well as two screw-in legs for the front of the machine. Run it without stepping on it to ensure it is quiet and no off-sounds are present then speed it up to ensure the same.
