What We Think

As with all things the JLL brand make the emphasis is on quality and affordability, the JLL S300 Treadmill is no different. With many of the features that more expensive models have this is a great value for money treadmill. Due to the current discount the value for money ratio is even greater.

The specifications are impressive there is a decent top speed and plenty of programs to keep users on course to meet their fitness goals.

Speed & Incline

The JLL S300 has a top speed of 16 km/h which is approaching the top end of treadmill speeds. In addition this model has the slowest speed setting out of all treadmills at 0.3 km/h making it suitable for the elderly and less mobile.

With 20 levels of incline users are guaranteed a hard workout. At the maximum speed and incline setting it is hard to keep the pace up for long durations of time, which is good for advanced users of treadmills.

Running Deck

Those that own or have previously owned a home treadmill will know how important it is to have a good-sized running area. A running deck that is too small leads to an uncomfortable workout, where you feel like you have to constantly adjust your running stride and arm movement to compensate for the lack of space. However, the JLL S300 has a very good-sized running area measuring in at 122 cm x 40 cm. A running deck of this size is good for those up to a height of about 6 foot 4 inches.

Featuring a built-in 16 point shock absorption system this treadmill is easy on the joints. In addition the absorption system reduces noise which is always a good thing especially if you have neighbours.

LCD Display & Monitor Functions

Compared to some running machines of a similar price the JLL S300 Folding Treadmill has a very modern looking LCD display. Simple to use and navigate even a technophobe would find it user-friendly. In total the display shows the users time, speed, distance, heart rate and calories.


There are in total 15 pre-set programs with this home treadmill with the first three been programmable to customise your very own workout. Having a wide variety of programs helps to alleviate boredom when working out. In addition it also means you are far more likely to exercise for longer.


Staying motivated during a workout is far easier when you have something to distract the mind from the task at hand, and what better way to stay motivated than listening to your favourite music. There are powerful speakers built-in to this treadmill and with the ability to hook up your iPod, iPhone or MP3 into USB the interface staying motivated shouldn’t be a problem.

“Machine easy to set up in 10 mins when delivered. I also like the folding option as my cats cannot sit on it when I’m not around. Very pleased. Delivery prompt as well and booked a delivery time which was helpful.” – Ms WAK


“It looks good. But it’s internal mechanical system that a obviously faulty because it doesn’t matter how fast or how steep your running or walking it stops which could cause an accident when it stops randomly at high speeds, I read reviews and as only a few customers said this fault was apparent I decided to go for it anyways but please be aware” – Susan
