Electric Folding Treadmill for Small Spaces - Ultra Quiet Portable Running Machine with 12 Programs & LCD Display | Perfect for Home Gym, Apartment Workouts & Office Exercise

I'm so happy my new treadmill arrived today! The instructions left something to be desired. I'm a pro at product assembly but some steps left me scratching my head. Nevertheless I was able to get it up and running. I still don't quite understand what the pull knob adjuster is for (pictured) so if someone wants to enlighten me I'd appreciate it.Once I got it moving I noticed the belt had an odd warping (pictured) but it isn't raised up and it doesn't seem to affect movement of the belt.It's the perfect size for my bedroom and will fit under my bed. The slight incline gives even a slower pace a little extra umph. I can't wait to use it, but for now I'm tired from putting it together so... tomorrow.So here's the thing...It was very easy to assemble and easy to fold up and store. it's easy to use and overall, i am very pleased with this tiny device HOWEVER it is NOT AS QUIET as advertised and I am BAFFLED as to WHY IS THERE ALWAYS DIRT behind and under this treadmill? I had lubricated it but it is still happening...hence the 4 stars. Will revisit this in another few months.Its a pretty decent treadmill, great for a small apartment. Gets the job done for sure. Also I saw someone comment on how they didn't know what the "pull knob adjuster" was for but I feel quite positive that its so the treadmill doesn't unfold when upright. I hope that helps if anyone else wasn't sure either ??‍♀️Works every day and is big enough for me... 6 foot tall 205 lbs. Its small enough for my wife 5'4" 140 lbs. Too easy to explain how it works. Includes heart rate, distance traveled, calories burned, time of use. Flat to the floor, so no baby hazards. I still turn it off before leaving the room.The treadmill arrived quickly and set up was easy. It is easy to use although the instructions are lacking in detail for lubrication of belt. There is a squeak that is constant while using the treadmill, it is very annoying. It makes me think there is something wrong or the treadmill is being damaged. I have not found any information on how to fix this, it certainly eliminates the claim of quiet in the product description. I would love the company to contact me on how to remedy this problem.Perfect size fit in space; as advertised and very easy setup and fast and ontime delivery. EASY mobility for a woman such as my self and easy setup. Purchased for in home for more walking activity becauce of No Gym access.This product is very quiet. I did purchase a rubber mat to protect carpet also very inexpensive. The Joy is now is now I can walk whenever I want 2-3 times a day without a mask, without pet odors or outside noise or Gym runners. Excellent PURCHASEWe are very happy with our purchase. The treadmill was easy to set up and is easy to move around as needed to fit in our small house.I am extremely happy with this purchase! The unit is small and quiet enough for me to watch a movie while I use it. I am 68 years old and can use the treadmill with great ease and at a comfortable speed. I have never been a workout or gym type person and yet use this treadmill very willingly. I would highly recommend this product.
