The JLL D100 and S300 are the company's best-selling treadmill models. While similar in their compact size and light weight, which make them suitable for small spaces, they differ in incline levels and some program/speed options. The D100 has a manual 1-level incline and 10 programs, while the S300 has 20 automatic incline levels and 15 programs. It also has a more cushioned running surface and larger water bottle holder. Overall, the S300 provides more varied workout options but costs £90 more than the D100 at £429 versus £339. Both are still affordable high-quality options for home use.

1. Which are the JLL best seller treadmills and why?
If you are on our home treadmill page and you are not sure about what model is more suitable for
you, this post may help you. Within our range of running machines, our best-selling treadmills are
the D100 and the S300. But, why are our best sellers?
First of all, the price that is very competitive. From just £ 339.00 you can get a proper treadmill for
home use which can be folded up for a really easy storage. So if you have space problems, this is not
a dilemma any more with the JLL home treadmills.
Secondly, within our range of home treadmills the D100 and the S300 are the models with the
smallest dimensions which again make them perfect for reduced space. Both are built on wheels for
easy transport.
And thirdly, the JLL D100 and the JLL S300 are the lightest treadmills within our home running
machine models with just 58 kg weight, so you can move the machine around with no problem at all.
But, what are the differences between the D100 and the S300?
 Incline is the main difference. The JLL D100 has just 1 level manual incline, while the JLL
S300 has 20 automatic incline levels. The incline on the D100 needs to be adjusted manually;
this running machine is perfect for those who want the treadmill for walking or running with
not much increase of the resistance. On the other hand, the S300 can be adjusted
automatically by a simple button touch while walking or running. It also increases calorie
burning and works different muscles groups than just exercising on the same flat surface.
 Programmes: The JLL D100 has 10 different running programmes and the S300 has 15
running programmes. It is important to mention that every JLL treadmill programmes are
divided in 10 sections where the speed would be increased or decreased every 200 metres
depending of the program selected. In both machines you will have the chance to re-set the
first three programmes according to your own goals.
 Quick speed buttons: Both running machines have the same speed range which goes from
0.3 km/h (the slowest speed on the UK market) to 16 km/h. However, the quick speed

2. buttons are different. While the D100 can select the speed at 3, 4, 5 and 8 km/h; the S300
just offers 5 and 8 km/h quick speed buttons.
 Running area: There is a small dimension difference on the length of both models. The D100
has 115 cm length, while the S300 has 122 cm.
 Price: I have to mention again the price with £ 90 difference between both models. D100
costs £ 339.00 and S300 costs £ 429.00.
 Cushion system: The S300 has a new design cushion system which makes exercising more
comfortable than D100.
 Item holder: The D100 running machine has a small tray, while the item holder of the S300
has more capacity which allows you to hold big water bottle.
