Sunny Health & FitnessPremium Smart Treadmill with Auto Incline, Dedicated Speed Buttons, Double Deck Technology, Digital Performance Display, BMI Calculator and Pulse Sensors - SF-T7515SMART

4/21/2022 - Update after using this treadmill for about a yearI 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 UpdateI 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 <g>).Update 2/21/2021I’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 2/27/2021I 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 4/1/2021I 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*

Use this every day to incline walk 45+ minutes at 3mph at 200+lbs. No issues after 3 months. Only thing I wish it could do is set up a couple of custom programs for walking, but I understand why it doesn't at this price. I'd for sure pay more for that feature though. If anything does break it should be pretty easy to replace the motor or whatever since it's super easy to access and parts are easy to get from the manufacturer. Will update if it ever breaks or when I reach a year.

It arrived on time. No damage. It is pretty heavy, but I managed to get it inside and assembled by myself. Most say it takes about 20 mins it probably took me 30-35 solo. And I’m a small 5’ woman.I can move it ok with the wheels. The carpet makes it a bit more challenging but still doable. It feels solid. Its very quiet. The tread gives me good space length and width. I like the programs. The incline is smooth and quiet. The controls on the side bars are a plus. I do use the bluetooth feature. The speakers could be better but are not bad. Not a lot of treble no feedback.The deck has good give/cushion/shock absorbers. Not hard on my joints. So far my only concern is when I’m going 3mph or faster there is a clicking sound. I don’t recall seeing that in any reviews. I’ve only had it about 5 days. I plan to use it daily for 3 weeks and see how things are at that time because free returns for 30 days, lol.I will update my review in 3 weeks. But so far so good no major complaints, just the clicking.

After extensive research for a smaller, foldable treadmill, I took the plunge and ordered this one. I was a bit nervous based on some of the negative reviews, but after three weeks of use I am happy to report that I am very pleased with this purchase. It came in great condition, although very heavy to move and bring the box inside - you will likely need two people for this. Set up was simple enough, as it's mostly put together (just need to screw a few pieces together). The machine runs really well, and I LOVE the automatic incline. That was the main reason I went with this model, as opposed to the others that I saw with strictly manual incline settings. I use the treadmill mostly for brisk, incline walking, so I can't speak to how well it handles running. That being said, it does go up to high speeds and I would feel comfortable giving it a try should I get that point in my exercise journey. The treadmill is relatively quiet when in use, and fit's in a nice corner of our home office. Should this hold up long-term, it will be one of the best Amazon purchases I've made. Don't listen to the bad reviews! This is a great product for the price.
