Sunny T4400
To start off I needed to keep up with a cardio workout after finishing a rehab program. I don’t like to cold weather so a treadmill was my option. Traffic where I live is like being on RT 95 in rush hour. So, with that said I started reviewing foldable tread mills as I don’t have a lot of space.I did a lot of research on size and cost and decided on this purchase. Shipped and arrived in 3 days. I was one of the lucky ones as it arrived undamaged.The hardest part of assembly was getting it out of the box. A monkey can assemble the machine. 10 bolts and its up and running. Folding running deck makes it possible to move around fairly easily.This is a simple treadmill. The deck is large and there is plenty of room to walk or jog. I was impressed with the size and space. The computer is user friendly and simple to operate. Large readout of speed, time, distance, etc. The preprograms are cool but I really haven’t used them at this point. The manual include is easy to change. I looked at Sunny auto incline but fewer moving parts leaves fewer parts to break. Folding mechanism is straight forward and works as advertised. The motor is a 2.2 hp and runs surprisingly quietly and smoothly even at higher speeds. The cup holders are big enough for a water bottle, so no complaints there as other customers have complained about. Tablet shelf is large enough to hold a tablet. A rubber mat under the machine is a must whether it sits on carpet or floors. Its not a heavy machine and along with the shock absorbers the rubber mat is a must.Lubing the machine is easily done and MUST be initially done prior to use. The factory aligned the belt and after several uses has stayed straight and tight. Include is the adjuster tool and instructions for adjustment if and when its needed.Overall, very happy with this purchase. Solid construction, small size but good sized deck and simple ease of operation makes this a good choice for the price range. This is not a thousand dollar plus gym machine. But if you are looking for a descent machine under $300.00 this machine is a good investment.

I am so glad I made this purchase!!!
I had a walking pad. Having stuck to using a walking pad, I decided to upgrade to a treadmill. My daughter had researched treadmills and suggested Sunny Health. I read all the reviews and purchased this one. I am very happy with this treadmill. It is very sturdy, and has a lot of power. The auto incline is so nice and adds a lot to the workout. It was easy to assemble only a couple screws. The pad is easy to adjust and lube. Controls are at your fingertips. And it folds up nicely for easy storage. You just tilt toward yourself and wheel it wherever you choose to store it. It has a hydraulic release for easy use. I am very satisfied with this product. I have suggested it to several people. The cost and value is a plus as well. Iâve waited to review this treadmill so I could use it and give it an honest review and I am very pleased with my purchase. I highly recommend it.

*UPDATE REVIEW – ONE YEAR LATER Sooooo happy!
*I am updating this since I’ve now had this treadmill one year (I bought it in December 2020): I STILL LOVE IT!!!! It still works perfectly. Admittedly, I didn’t use this treadmill much in the summer months since I was always outside but, for the past three months, I’ve been using consistently every night or every other night. Please note, I do NOT run on it. I only use it for walking (sometimes very fast walking). I keep the belt lubed up and I keep it clean and I have had ZERO problems with it. The price was great, the size of the treadmill is great, and I love that it fits in my living room so I can walk and watch TV at the same time. I still hate the height of the handlebars. I continue to hit my wrist with my Fitbit on it unless my arms are at a 90 degree angle.(from when I bought it in December 2020: I’m so excited! With crazy delivery delays and treadmills running out of stock because of the holiday, I ordered this Thursday night and it was just delivered a day early! It’s so cold and rainy here in northeast Ohio and I’m going crazy being stuck inside instead of out at the parks hiking. First, I’ll say, I am a female, 52 years old and I unboxed and put this thing together by myself in about 15 minutes. Couldn’t have been easier! The instructions look scary, so just know all you need to do is screw in about 10 screws and that’s it. Watch a You Tube video to see exactly what to do. I made sure the folding mechanism worked (it did), I switched the incline (also super easy), I lubed up the belt (make sure you do that before using) and I adjusted the belt a bit (it was over to the left). All very easy to do. Powered it up, jumped on and I am in heaven! Belt size is great, the handlebars don’t bother me or get in my way at all (I’m 5’6″). Console is clear and concise and there are two cup or phone holders. I’m about to take it for a spin right now so I’ll update this review after I’ve had it for a bit. So far, it’s perfect!!Update: I’ve used this treadmill everyday walking 2 miles a day. It works great and I have no complaints EXCEPT some other reviewers are correct, the handlebars are in the way. I always hit my wrist and my Fitbit on the left bar while I walk. I so wish they were a bit higher or lower. So, unless your arms are at a 90 degree angle the whole time, you’ll probably hit the bars with your hands. Not the end of the world. Everything else is great.

Hace un año (agosto 2023) compramos esta caminadora después de varias comparaciones.Y ahora después de poco más de un año (nov 2024) de uso casi diario (se usa por dos personas 45 minutos cada una, de martes a viernes, en ocasiones domingo también) sigue funcionando perfecto, solo hay que lubricar periódicamente cada 2 meses aprox con un Lubricante de silicon de buena calidad y listo!No es ruidosa, lo normal comparada con la de cualquier gama.Objetivamente muy recomendable.

The first unit I received had frame damage in transit but Amazon made good, getting me a second unit at no additional expense. I have just finished assembling the new unit and haven’t had a chance to try it out yet – I’ve still got to lubricate the belt before giving her a spin, so my four-star rating may change up or down. But the design seems pretty sophisticated; the treadmill has most of the features I really wanted, and my main problem assembling it was making the whole process more difficult than it needed to be. I got this model, because it has excellent reliability reviews, and I figure that the more complicated models, with automatic grade adjustment, for instance, might be more likely to have issues. The pic shows the unit in the “folded” position and reduces the “footprint” of the unit to about 3 feet x 3 feet on the floor. Fit and finish seems tight and handsome, appreciate the two cupholders and holder for a tablet or digital phone. I think most treadmills are too heavy and bulky for this senior female, but I liked this one being lighter and more compact – still a quality unit and I was right that I was able to assemble it by myself – although it would have been nice to have a second pair of hands at one or two points! All in all – so far very happy.Update – I’m raising the overall rating to five stars. I finished lubricating and adjusting the belt and have had two sessions of “power walking.” The treadmill is quiet – my neighbours in the other side of my semi-detached house won’t be disturbed by noise or vibration. (And to make doubly sure, I have installed a folding mat under the treadmill, which is recommended.) It is easy and a joy to raise the unit for storage and lower it again for use. I am really glad that I chose this model on the basis of the reviews and Amazon’s recommendation, because if I had bought elsewhere, I probably would have purchased a much bigger, clunkier and more expensive unit, Highly recommended!

Buena, llevo casi un año y no ha fallado, aunque tampoco se ha usado mucho

I’ve been using this for quite sometime, the assembly was easy and the rollers (when the treadmill gets stowed away) makes it a breeze! It runs great, and hasn’t had any issues performance wise since using it for over 100 miles so far.Only cons I have are the cupholders not being able to hold a cup and the inability to adjust the metrics from Miles to Kilometres. The incline is manually adjusted which isn’t an issue unless you’re a super serious runner that relies on those metrics. Lastly, the belt does need a bit of tuning before it straightens out, but even if it goes a bit to the left or right it still runs fine.This treadmill maxes out at 9MPH which is pretty standard, the track looks narrow but thats because it doesn’t have the incline feature built in so it actually saves space.Overall, perfect for a at-home runner on rainy or winter days, definitely worth the price!

This is a smaller sized treadmill that only runs up to 6mph and is a quality and sturdy product. It is narrow and shorter than treadmills used for running. But jogging is possible. I use it for only walking at a brisk pace. It comes nearly assembled. Through there is some necessary steps to get it functional, it is not difficult. It has run perfectly for over a year with frequent use. It does not have the bells and whistles in higher priced units but is more than sufficient for my purposes. (I use silicon spray to keep the track lubricated and running smoothly.) I have no complaints and appreciate the smaller footprint it takes.
