Sunny Health & Fitness SF-T7603 Electric Treadmill comes with a 2.2 HP peak DC electric motor. Motor of this strength is not dimensioned for heavier runners, which is confirmed with an official maximum user weight of 220 pounds (100 kg).

Running surface dimensions are (L x W) 49 x 16 inches (~124.5 x 40.6 cm), which is suitable for shorter runners and most walkers. Depending on the stride length and running technique, even taller people can use this treadmill, but for them, roomier treadmills are recommended.

SF-T7603 treadmill dimensions (L x W x H) are 62 x 27 x 47 inches (~158 x 69 x 120 cm) and it weighs 103 pounds (~47 kg). SF-T7603 treadmill is a compact, foldable unit, not requiring much space for workouts or storage, and thanks to the transport wheels, it can be moved around easily.

Personally, like many similar units, it is highly recommended to position the unit on the permanent location, with or without a good treadmill mat, and use it whenever you have time - out of eyes, out of heart :)

SF-T7603 treadmill comes with 9 built-in programs and with a heart rate monitor. Heart-rate contact sensors are positioned on both handles.

The console is simple to use with large buttons - note that some of the controls are positioned on the handles too, for easier use during walking or running.

LCD displays basic information about workout sessions, like elapsed time, covered distance, walking/running speed, and estimated burned calories.

On the other hand, the incline is manual, so the user has to stop with the exercise, change the incline level, and then again proceed with the exercise. Personally, I don't like to stop my cardio sessions and if the treadmill doesn't have a motorized incline, I walk/run the entire workout on the same incline level. But, changing incline level from session to session can be beneficial too, for varying intensity and thus for better workouts.

The safety pin is positioned in the middle console and it is highly recommended to use it every time. Why? Well, just go to YouTube and look for treadmill/gym accidents and you will see why :)

The speed range is between 0.5 and 9 mph (~0.5 and 14 km/h) and is enough for walkers and most casual joggers/runners. A faster treadmill capable of supporting heavier users requires a stronger and thus heavier motor and frame, leading to a higher price and weight of the unit.

SF-T7603 treadmill is a foldable unit, requiring rather little space when folded. The unit is equipped with an easy folding mechanism with a soft drop system. It helps the user to fold and unfold the treadmill quickly and easily.

It comes with 90 days manufacturer’s warranty - not bad for such a unit, but it could be better. When the unit arrives, it requires assembling and lubrication before first use. Assembly is not very complicated, but if you are not a DIY person, order an 'Expert Assembly' service - certified technician will assemble the unit for you, lubricate the belt and show you how to use the unit.

In any case, read the manual first.

Long Story Short - Sunny Health & Fitness SF-T7603 Motorized Treadmill is a very good and affordable home treadmill. When the maximum user weight is not an issue, the SF-T7603 treadmill is a very good choice for periodic cardio workouts in the privacy of your home.
