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.

A great budget-friendly treadmill! Buy it!
This is a great treadmill. I read many reviews and spent a long time to decide on an under $500 treadmill. This hasn’t disappointed and it’s been about a month. I use this daily at a full sprint and regular walking/jogging as well. Like most treadmills in this price range, the belt width was something i didn’t want to compromise on. I was weary after experiencing much wider belts at the gym, but this belt size didn’t impact my running or workout. The quality is nice, it’s heavy and well grounded. The panel is plastic and definitely not ‘high-end’ but unless you’re expecting this to wow people with design, it’s not even an issue. Easy to fold up and a cool slow release to fold back down. Just measure out your room and understand this will need a corner to hang out in as it doesn’t fold completely down to hide under a bed or anything like that.Pros:-Easy to assemble. The box was a bit heavy – so have some help or get a dolly to help roll it around. It was well packed and even with a rough looking tear in the cardboard, the treadmill was nicely protected with foam, plastic wrap and more cardboard. Took maybe 30min to set it up.- The folding makes it easy to store in a corner and not take up space when not using. It’s in my home office and doesn’t crowd the room at all.- Simplicity. You turn it on and just go. The speed programs are nice, but lets be real, you’re gonna be adjusting the speed manually most of the time. The screen is well lit, bright and has the basic information you need. Time..speed, distance..calories burnt etc..- The speed controls are also on the right handle which is very convenient. Also, on the left handle, a basic Start/Stop option. I rarely touch the actual panel in the front to adjust speed or turn on.- The belt seems to be strong and it is easy enough to lubricate. I had to tighten the belt after feeling like it was slipping at a full sprint, but with the allen tool they provided, it was a very easy and simple fix. There are plenty of videos on youtube that will show you how to properly do this, as well as the user guide.- It runs quiet but once you start running it’s a bit loud. But you’re running on a metal board…so get headphones or turn on music.- You don’t need to have some monthly subscription to actually use it. It is a basic treadmill. Start it. Run on it. Get fit. Find training videos on youtube.. they’re free and effective.Cons:- The heart rate monitor doesn’t seem to be accurate at all. I don’t really care much about this especially since i use a fit bit. Again, it’s not the point. You use this to run on. Keep your expectations within your price range.- Manual incline – but again, not a deal breaker. If you’re wanting automatic/advanced inclines, you won’t be spending under $500.- Handles have rough ends and sometimes while in a sprint, my hands/arms might graze them. It’s not hard plastic, but just rough padding ends i guess. A bit annoying but nothing serious.- The two cupholders are a bit shallow, but they easily hold a typical bottle of water in place even when running on it.- It has an area for you place a tablet on the main panel, but it’s not that large. I place my phone there though with no issues.Overall, it’s a great entry level treadmill to have around your office or home gym. I enjoy walking on it, doing some HIIT exercises on it and jogging. I will always prefer real running, but this is a great option for cold weather and rainy days. The price is great, and it delivers a solid option to get into shape. Whether you choose this or another, don’t get analysis paralysis! Get it ordered and on the way so you can hit those fitness goals!

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!

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.
