The inclination possibility is also quite high with a 0-12% inclination feature, and it is automatic, helping us achieve different inclination levels without stopping in between exercises.

Frame and Construction
The SF-T7515 machine not only looks sturdy but boasts of being utterly stable as it comes with a steel frame that can support individuals as heavy as 250 lbs.
You can find the company’s logo, Sunny, painted in bright red, while the rest of the machine has a corrosion-resistant white finish that’s sleek to see.
Besides this, there are several parts made of ABS, such as the motor cover, the deck’s side rail covers, and also the covers present between the console masts and the base of the frame.
When completely assembled, the unit is almost 120lbs which undoubtedly proves its stability and sturdiness. This might be a surprising factor to some, given its small size.
Such a profound weight makes the treadmill much heavier, and hence, don’t think of carrying or assembling the equipment on your own. But once the treadmill is completely assembled, there should not be any trouble relocating it to any room of your choice as the manufacturer has been indeed clever to fit two wheels that help in transportation.
The presence of adjustable stabilizers at the base further enhances the overall stability of the machine.
Being mainly designed for walking and jogging, the SF-T7515 doesn’t occupy more than 64.5 inches in length and 28 inches in width when fully assembled.
But, for better comfort and safety, it is better to leave a two-foot clearance space on the sides and at least three feet at the rear.
Another major advantage of the machine’s construction is its foldable nature, making it easy to lift and lock the treadmill in an upright position without strain.
The soft-drop hydraulic mechanism makes the folding/unfolding mechanism easy and safe without any damage.
When folded, the unit measures 40″L x 28″W x 55.5″H.
Running Area
A treadmill’s running area is extremely important as this is the main part of the machine that aids in your comfortable exercise routine.
The walking area of the SF-T7515 treadmill measures 49.5 inches in length and 16.5 inches in width. Hence, there is no need to worry about exercise space, and even individuals as tall as 6 feet 2 inches in height can use the platform.
The only word of caution here is that while tall people can easily use this machine, they must ensure to take care of their stride length to work out comfortably.
Sunny might not have provided any advanced cushioning system, but there are numerous shock absorption points as compensation. These points reduce the impact on the knees and joints, minimizing any stress to these parts.
Incline
The Sunny SF-T7515 treadmill comes with a motorized incline system, making it easy for the individual to change the inclination angle while exercising.
The digitalized inclination adjustments can be operated from the machine’s console or even from the left handlebars where the control options are available.
There are many built-in workout programs, and in case you decide to use any of them, the machine attends to the incline needs adjusting the deck’s angle automatically.
With 12 different levels of inclination adjustment, it is possible to set the machine at any angle between 0 and 6.9 degrees (0-12%). A 1% inclination increment is possible with the help of the gradual adjustment controls that are available in the leftmost corner of the console (left handlebar).
You could even choose from quick incline controls that allow an inclination angle of 3%, 6%, 9%, and 12%.
Step-up Height
The step-up height of the machine is a strong determining factor in whether or not the treadmill could fit in your height comfortably.
SF-T7515 has a maximum step-up height of 10 inches. Hence, when the machine is set at its maximum inclination position, the deck elevates by a couple of inches in height.
To avoid any head collisions and for maximum safety, it is recommended that the machine is placed in a room where the ceiling height is at least 15 inches higher than your height.
Motor and speed
While the frame, construction, and mechanism are optimal, the motor is a light-capacity one with a power of 1 HP.
Still, this capacity is good enough for walking and jogging. The machine also doesn’t succumb to heating and promises a good performance at the maximum possible speed.
The SF-T7515 is a motorized treadmill and hence, requires a power circuit to start functioning. The manufacturer has taken care of this requirement and has provided a 3-foot long power cord along with the unit, and this cord must be attached to the front part of the deck.
Don’t worry about excess electricity bills. The motor is not a very powerful one and hence, doesn’t shoot up the bill value considerably even when the machine is used regularly for long hours.
The maximum speed the motor can go is 8.0 MPH (12 km/h). The base speed stands at 1.0MPH, and from thereon, it is possible to adjust the speed in 0.1 MPH increments.
Such fine speed adjustment options help us make precise choices, match our pace with the belt’s speed, and experience a comfortable walking rhythm.
It is possible to make speed adjustments from the console and also from the right handlebar. Apart from gradual speed adjustment, it is possible to make quick speed choices of 2MPH, 4 MPH, 6 MPH, and 8 MPH.
As we are working out in a home gym setup, we must take utmost care to avoid disturbing others while working out. The SF-T7515 model makes this possible and enables us to work out anytime during the day as the motor generates negligible noise.
Console
The SF-T7515 treadmill comes with an average console that’s neither too basic nor too sophisticated.
Any console primarily serves the purpose of helping us with detailed metric values, and for this, the screen must be visible. An LCD with a bright blue LED backlight improves the readability of the screen.
The console is divided into various sub-sections, and every section shows a detailed display of various metric details—hence, this negates the need for scan functionality.
We can track various values such as time, speed, calories burned, pulse, and incline range.
For each of these values, the manufacturer has provided us with the option to set target goals and achieve our desired fitness levels. All that we must do is select the target value for any of these metrics and start working out while the console takes utmost care to initiate the countdown back to zero.
It is seen that the console is Bluetooth-enabled but reading the pulse using an HR chest strap transmitter is not possible.
So, how do we read the pulse? It’s simple. The sensors present in the side of the handlebars help us read the pulse besides promoting an HR-based program.
Feel free to sync the console to your smartphone and enjoy talking over the phone. Even better, take them via the speakers that come along with the treadmill, all of this while exercising vigorously on the machine.
But, the console is not iFit-compatible, which prevents us from using any fitness app for storing and monitoring workout data.
Besides choosing the speed and incline levels manually, the manufacturer has integrated 12 prebuilt programs for better challenging levels.
Each of these levels takes care of speed and incline adjustments as per their difficulty range.
Up to three user profiles can be created. Each of the individuals using the profile can modify the program by choosing the desired value for the 10 segments and saving the changes for using them later.
If you wish to know your Body Mass Index value and make health goals accordingly, the machine presents the BMI feature that takes the individual’s data such as height, weight, age, and gender and presents us with results.
Besides such optimal primary features, the treadmill is fitted with a good number of secondary features such as the tablet holder, sound system, and dual accessory trays in the console’s dashboard.
Use the sound system to listen to music using the smartphone or MP3 player via Bluetooth connection or the audio jack input. It is possible to play, pause, switch tracks, and change volume using the console.
Combine entertainment with exercise using the tablet holder available between the controls of the console to watch videos.
In between workouts, if you feel famished or dehydrated, try sipping some water that could be placed in the water bottle holder.
Assembly
While setting up a home gym seems fun, the most dreaded part is assembling the fitness equipment. Sunny’s SF-T7515 doesn’t disappoint us in this regard as the treadmill comes fully assembled.
The package arrives folded in a flat position. It is necessary to unfold the console masts and set them up vertically to use them. All the necessary screws and the basic toolkit are provided along with the package.
A user manual provides all the details essential for setting up the piece of equipment.
All over, the assembly should be done in well under 30 minutes.
Maintenance
The treadmill requires frequent lubrication to keep the running belt in smooth working condition.
It is also essential to keep the motor free from dust particles or fiber, failing which the machine might not stand up to its desired performance.
Also, check for loose parts and bolts periodically.
