    4/21/2022 – Update after using this treadmill for about a year
    I use the treadmill 4 to 5 times a week for 2.5 miles at 3.5 MPH over varying inclines from 0 to 3. The treadmill has been flawless so far. Highly recommended.
    End of Update

    I also would NOT get a treadmill without auto incline. Doing it manually means getting off the treadmill and manually adjusting a plastic piece at the rear of the treadmill.

    Belt width on this treadmill is 16.5″, length is 49.5″. I’m 5′ 10″ and if not careful (and my feet move towards the rear of the treadmill a little). I can feel where the belt is joined. Staying a little forward avoids that.

    Very easy to assemble comprising 6 bolts with lock washers and 4 screws. Their screw driver isn’t much good, I would use your own. They provide two allen wrenches of slightly different sizes but only one size is needed.

    The treadmill appears very sturdy, easy to fold up, easy to let down again. Bluetoothj speakers work OK to my Android phone. Not great speakers but wouldn’t expect them to be great (after all, it is a treadmill). The speakers are certainly listenable to.

    The treadmill motor is very quiet also.

    I did purchase the mat by Sunny that the treadmill sits on.

    Per the instructions, I did lube under the belt before use. Probably worth ordering more when you order the treadmill. Using more than 5 hours per week…they recommend lubing monthly.

    All in all, a very good treadmill (not that I am any expert ).

    Update 2/21/2021
    I’ve used this for the last several weeks now. I really like the treadmill. Seems to be well made, was well packed. The only very minor gripe I have is that between my phone volume control and the volume control on the treadmill it is a little difficult to get the volume just right. Either a little too soft or a little too loud. Not a big deal. The treadmill really needs a more granular volume control.

    Update 2/27/2021
    I don’t take any stock in the pulse readings. I see wildly fluctuating numbers given during various times during my walking sessions. I walk 2.5 miles at 3.5mph 6 times per week. I see pulse fluctuations from the 80/90 mark after, say 1 mile, and release my fingers or thumbs from the handles. 20 or 30 seconds later, when testing again, I see figures in the 120/130 range and once as high as 170. 20 or seconds later it is back to 80/90. Doesn’t make sense to me.

    Update 4/1/2021
    I sent an email to the manufacturer about 4 weeks ago. I had an observation about the display showing “Fat” and the manual showing “BMI” as well as asking a question about programming custom treadmill programs. As of today, I have had NO REPLY. Makes me wonder what would happen if I had a warranty claim (I don’t ATM). Still not a good indication of support from the company. Lowering the rating to 3* due to this.

    6 month (or so) update.
    Having used this treadmill for around 6 months, I have raised the rating to 4*. The only real issue that I can mildly criticize is that the volume steps seem to be too far apart to get the volume to a level that I am OK with. It’s either a bit too loud or too soft. I have played with the volume on both the treadmill and my phone but can never seem to quite get it right.

    All in all, not much of a criticism hence raising the review to 4*

    Back in the 2009 I had ordered a Weslo treadmill and loved it. It had an auto incline and was just simple and basic. Nothing really fancy but that’s all I really needed. I’m not a runner you know… I just like walking and maybe a light jog. Easy cardio/calorie burn. Anyway. So I got rid of it when I moved and had regretted it since because I could never find another like it. They discontinued it and the other weslo treadmills didn’t have auto incline. This machine is the same, but looks a lot nicer looking, basic and perfect for someone like me.
    If I had the money he I may have gone fancier…….

    I just had my husband assemble it which was a little of a pain as tightening the belt and lots of styrofoam crumbs……. But so far it’s all in one piece and wasn’t broken like a lot of peoples have been. I do have a large ding on the metal in the back and one of the wheel covers in the back is flipped upwards…… cosmetic, but you know, when you buy something and spend $500 you want it to look brand new right? I’m going to see if someone can reimburse me a little for it being messed up, but I’m not holding my breath. Not enough to send it back of course, but again…… when you spend money you want things to arrive pristine. Anyway. I’ll update as I start using it and if I encounter any issues. But overall what I wanted.

    While the treadmill works just as it should, due to the way the item is packaged it takes damage in shipping very easily. My treadmill came with two cracks in the plastic but fortunately the cracks did not cause any functionality issues just aesthetics. Was able to chat with Amazon and get 25% off due to the cracks. I could have sent it back and tried again but i cant imagine how hard it would have been to try and ship this back. I do like the treadmill though and am happy with my purchase!
