It offers many of the basic and advanced features that we see in much higher costing pieces of fitness equipment. The people using this item are more than impressed with its performance. When you are trying to set up your home gym, space can be a major issue. This item is going to fit much better than most other treadmills and you can fold it up when you are done to clear up space for other activities. Maintaining a strict cardio routine is imperative in maintaining proper health. It also plays a big role in your progress in other activities like boxing, mixed martial arts, weight training, and more.

With the fact that it is not super heavy, you won't have to worry about an extra set of hands to relocate it.  The running surface is quite small. If you are exceptionally tall, this may make running on this piece of equipment difficult. Overall, this item is a suitable option for a lot of people and you won't have to worry about over-extending yourself financially to own it.

Basic Features

We were a bit surprised to see all of the basic features that this product offers considering its affordable price. You will have your choice of two separate cup holders so that your water bottle is easily accessible through all stages of your routine. This design also offers simple controls. You can start, stop, increase the speed, or decrease the speed all of the push of a button. In addition, you will be able to easily choose from a variety of different programming options. This treadmill is also easy to store. Simply fold it up and push it to the side to give yourself extra room for aerobics, heavy bag practice, grappling, or basically any other variety of activity that requires a bit of extra space. They also include rollers at the base so that once it is folded up it is exceptionally easy to move around.

Advanced Features

At this price point, you don't expect many Advanced features, however, this one provides quite a few. It has an LED display that will provide you with information like how many calories you have burned and how long you have been working out. You can control not only the speed not only on the console but also on the side handlebars. This is a very convenient feature. In addition, you can start and stop this treadmill from the handlebars. Listening to your music while you run is exceptionally convenient when you use this item you can plug your device into the aux Jack and listen to it through the income it's all speakers. It has been noted by customers that the speakers are not the best quality, however, they do offer good volume. The ability to listen to music while you workout can truly help improve your performance. This item also has a pulse sensor so that you can find the heart rate zone you wish to Target. whether you are looking for a good cardio routine or maybe to burn some fat this product will help you target it those heart rate zones easily and accurately.


It was a bit surprising to us that this product does not offer any type of incline feature. Due to the fact that there are so many built-in programs it seemed odd that there is no incline. Upon further investigation, we have found that the programs increase in speed as you work through them but not an incline. This can have a negative impact on the intensity of your workout as working on an incline really does provide a challenge. For those of you that are exceptionally physically fit, you may not find that this treadmill offers you enough challenge because of its lack of incline. You will be able to improve how many calories you're burning, your strength, and your speed while working on this treadmill but it is not going to do as good a job at building muscle as something that offers incline options would.


You won't be getting as comfortable of an experience with this treadmill as you will many others. Some features that we commonly see that is missing with this item are things like a built-in fan and handlebars that run farther back the machine. The deck of this treadmill is also quite stiff. You will not get a lot of rebound which could leave your muscles and joints feeling sore. If you are the type of person that likes to hold on to something while you are walking and running your options on this machine are limited. There is only one set of handlebars and they are not very long. Holding them could lead you to kick the front of the console and messing up your pace or possibly sustaining an injury from slipping or falling. Overall, this is not going to be the most comfortable treadmill to run on.


At its lowest rate of speed and where it starts out, is that about a half a mile per hour. You can increase the speed up to just over six miles per hour. This is not nearly as much speed as many other treadmills will offer. Those of you that are super into fitness and running may not find that this product offers you enough speed to truly challenge you. In turn, the programs may be quite useless if you don't find the speeds to be appropriate. Consumers have noted that they felt it did not give them an adequate challenge. For many people, speeds between a half a mile and 6 miles an hour are more than enough. It is important to think about how you perform currently before deciding whether or not this option will provide you with a difficulty you need to continue to move towards your goals.


As previously noted, this product is not as big as other treadmills you may have been looking at. It does offer a decent-sized belt but it has been mentioned that it may not be long enough for those of you that are very tall and have long stride lengths. Unfolded this product is just over 56 inches in length. This is quite a bit smaller than your standard treadmill. The width of it is also smaller than what we typically see. It comes in at just over 25 inches. this item can hold up to 240 lbs. It is important to note that this is significantly less weight than most treadmills can handle. If you are well over the weight capacity you will want to look for different options as it will impact the durability and functionality of this product.


Most consumers feel as if this product is pretty easy to assemble. There are not a plethora of pieces and most of it is already put together when you receive it. You'll get all of the tools required to set this piece of equipment up. There were no mentions from customers that they needed to use their own tools due to the poor quality of the ones that come with it. The instruction manual offers great diagrams. As for the instructions themselves, there were some mentions from consumers that they felt they were a bit frustrating and hard to follow. Overall, we do not feel as if you're going to need to worry about expert assembly to get this product put together correctly. All you need to do is stay calm, work slowly, and take the time to read through the directions prior to starting assembly.

A couple of other things that consumers are not overly pleased about is the lack of power and incline. When you are truly looking for a challenging routine this treadmill is likely going to fall short.


Honestly, the value of this product varies. While it is exceptionally affordable and will fit into most budgets relatively easy it is not going to provide a great challenge to those of you that are active runners or quite physically fit.
