Sunny Health & Fitness SF-T4400 Treadmill

Sunny Health & Fitness SF-T4400 Treadmill is one of the most popular and very affordable home treadmills. When compared with larger, heavier and more expensive units, it does have certain limitations, but for most home runners and walkers, it provides an opportunity for great cardio workout on daily basis.

Sunny SF-T4400 treadmill is powered with 2.20 Peak HP electric motor which enabled speed range between 0.5 mph and 9 mph (0.8 - 14.5 km/h). Such speed range is acceptable for most walking and jogging exercises, while faster runner should choose stronger and faster treadmill.

Note: this is 2.20 Peak HP electric motor, not CHP (Continuous HP) electric motor. Stronger motor would allow larger maximum user weight and higher maximum speed, but it would also require more electric power, treadmill would be heavier, and it would cost more.

Sunny SF-T4400 treadmill requires 110V and 18 Amps to operate. Its maximum allowed user weight is 220 pounds (~100 kg) and it could be larger, but this treadmill is designed for lighter people and elderly.

Unit weighs 103 pounds (~47 kg) which is similar weight for units in this price range, designed for users bellow 220 or 250 pounds.

Consoles is easy and simple to use. Sunny SF-T4400 comes with 9 built-in programs (plus 'Manual Mode' option), speed can be increased/decreases in 0.1 mph increments or user can use 2, 4 or 6 mph buttons (walk, jog, run). Also, pressing stop button once, pauses workout session, keeping the current data and statistics. Very nice feature for busy people who get interrupted almost on regular basis (people with kids know what I am talking about).

Console displays time of the exercise, covered distance, estimated burned calories, current pulse and of course, speed.

Console also has smart phone or tablet holder, but when placed, smart phone/tablet covers main LCD display. Also, SF-T4400 features built-in Body Mass Index (BMI) calculator.

Bottle holders are on both sides of console, helping the user stay well hydrated during cardio sessions.

Handrails help the user to start and stop exercise and to control parameters of the workout session. Handrails are not too long and they don't limit the user's space during the exercise.

Note: there are no USB charging ports, no cooling fans, no user profiles and no speakers.

When folded, unit's footprint is significantly smaller (L x W x H): 34.5 x 27 x 58 inches (~87.6 x 68.6 x 147.3 cm). Note that Sunny SF-T4400 comes with 'Soft Drop System', enabling the user to safely and easily fold and unfold the running deck.

Also, Sunny SF-T4400 comes with built-in transport wheels for moving the unit around, if required. Personally, such equipment should be positioned on permanent location, on a good treadmill mat and used whenever one finds time.

Running surface is 48.82 inches long and 15.75 inches wide (124 x 40 cm) and it could be roomier. But again, with 220 pounds limit, such running deck is long and wide enough for most walkers and joggers. Shock absorption during exercise is very good - very important for both healthy people and those having issues with joints.

Incline levels can be changed, but only manually, requiring the user to set the incline level before the exercise or the user must pause the session, change the incline level and then continue with the workout session. Incline levels are 0%, 2% and 4.37%.

Many treadmills offer much greater incline range, but such treadmills also have running deck well above the ground.

Warranty conditions: "Sunny Health & Fitness warrants its products to be free of manufacturing defects in materials and workmanship to the original owner/purchaser of the product for standard household use."

Structural frame comes with 3-Year warranty, while other parts and components come with 90 days warranty.

Warranty is acceptable for the treadmill in this price range - after all, if it is free of manufacturing defects, it will last much longer than 90 days, when used at home.

When the unit arrives, it must be assembled and lubricated. Assembly is not complicated, just be sure to thoroughly read instructions/manual.


Long Story Short - if shortcomings of SF-T4400 treadmills are not problem for you, consider this treadmill as a good and very affordable home treadmill.

Don't forget that main cons are: 220 pounds maximum user weight, no user profiles, 9 mph maximum speed, 48.82x15.75" running deck, short warranty for motor, rollers and other parts.
