This unit also comes with built-in speakers, a high-end console, and efficient Bluetooth connectivity. But, there are a few things that we do not like in this model, and it is important to highlight them for you. After all, nothing in this world is perfect.

Dimensions and Assembly

This fantastic treadmill model has the following dimensions: 

  • L62xW28xH50 inches

It is fair to say that this size is adequate for a majority of spaces. However, some customers have issues with this unit’s large footprint. According to them, if you have a small home, you might find it hard to accommodate this machine. 

Other than the size, the JLL T350 treadmill has an ample weight of 59kg. This is a heavy machine, so even if you have to pay extra for delivery, do it for your own ease. It is pretty hard for one person to hold the machine and settle it in its rightful place. 

But despite the issues that high weight and large footprint can create, these factors are true representatives of this machine’s exceptional durability and longevity. 

Delivery and Setup

The delivery of this unit is prompt and easy. The brand doesn’t believe in delays, so you will get your JLL T350 on the time promised. 

Since this unit features a soft-drop technology, unfolding it is just a piece of cake. Moreover, assembling is quick and easy too. You can go through the well-written instruction manual for any guidance required. 

The treadmill comes with transport wheels. So once you have fully assembled the unit, you can carry it to your storage room with ease. However, if that place is upstairs or in your basement, you may require some help to carry this unit. 

Console and Data Tracking

JLL T350 Treadmill Console

Once you have correctly set up your treadmill, the first thing that you will notice is the unit’s quite attractive 5 inches LCD screen. 

This console is a reflection of advanced technology that most users will love. For instance, it comes with a touch-sensitive screen which means that you do not have to press any buttons. 

Besides, the display shows all the parameters of your performance, thus helping you to keep track of your goals and aim more for better results. For example, you can read the screen for speed, time, distance covered, heart rate, and calories burned during a workout. 

The console features 20 running programmes, and three of them can be easily customised. That’s a great thing for people who might be beginners and hesitant to follow even the basic plans offered by this unit. 

Right below the console, there are two built-in speakers. You can choose to connect your MP3 player to the port, insert a USB Flash drive or use the Bluetooth-enabling feature to play your favourite playlist. The speakers offer good sound quality and eradicate the need of using your tangled headphones while working out. 

There are two handlebars on this treadmill that are also a part of the console, so it is imperative to mention their quality. They are solid and well-made. But most importantly, they come with pulse sensors. 

The heart sensors help measure your heart rate while you are working out. You can connect these sensors to a workout program so that when you train, the treadmill adjusts the speed according to your comfort. 

Speed and Incline

The JLL T350 treadmill model features a 2.5HP motor that can easily produce a peak power of 4.5HP. That’s quite an exceptional performance and works brilliantly for both beginners and intermediate trainers. 

This motor can produce a maximum speed of 18kph. That’s quite adequate for low and medium-intensity workouts. But if you are a professional who wants to perform a HIIT workout or jog at a fast pace, the unit may fail to accommodate you. 

However, you can always adjust the treadmill at its highest incline levels to make your training challenging. The JLL T350 treadmill offers 20 incline levels which are hard to find in most budget-friendly machines. You can automatically activate the incline levels with a simple touch on the console’s screen. 

Design and Folding Mechanism

Simply put, the JLL T350 treadmill is a good-looking unit. Made with alloy steel, the treadmill model exhibits excellent durability and strength. 

It has a weight capacity of 120kg, which is more than enough. However, if you are a heavier individual, you might want to get a much more solid unit for your workouts. 

This treadmill model has secure and solid parts with a well-designed belt. So, even if you want to run or perform a challenging workout, the machine won’t shake unnecessarily and ruin your experience.

The JLL T350 is an all-black machine. The chic finishing with smooth edges makes this unit perfect for all ages and genders. Besides, its beautiful console is one of the greatest highlights of the whole design. 

As mentioned earlier, the JLL T350 features a folding mechanism which makes it worth your money. The soft-drop folding feature means that you do not hurt your fingers while assembling the unit. With only pressing a button, the treadmill opens up efficiently without you putting much effort. 

Besides, the presence of a folding mechanism also ensures that you can store this unit easily in your tight space. You can either place it in a corner or fix it under your stairs. When folded, this treadmill doesn’t take much space and gives you the liberty to use other workout units as well. 

Running Deck 

If you prefer a large amount of workout space for running, the JLL T350’s treadmill won’t disappoint you. It comes with a reasonably sized deck with a length of 47 inches and a width of 16 inches. 

Besides, this 16-point cushion deck feels pretty soft on your feet. The cushioning technology helps absorb shock and reduces impact. As a result, you feel no pressure on your joints or knees while you work out at your chosen pace. 

This technology also acts as a motivator for beginners. For instance, the high comfort level allows you to experiment with the speed and make the workout more challenging. 

When compared to other running decks, the JLL T350 features high-quality silicone rubber. This material is quite efficient with shock absorption and reducing impact. In addition, the cushions help reduce noise with every step, which means your running won’t bother your family or neighbours anymore. 


The JLL T350 treadmill is a noiseless unit, but according to some customer complaints, this treadmill makes a terrible noise as soon as you start the motor. The belt also creates an annoying sound when it moves at a specific speed. 

If you face any of the above issues, you should always recheck the unit’s assembling and adjustment of parts. It usually happens when the motor is crooked, so in that case, get in touch with the brand’s customer service office as soon as possible. 

Noisy machines are not only a distraction for you but also annoy your neighbours and family members while you work out. So, if you do not want to face that issue, try the machine as soon as it arrives and share your feedback with the brand. 

Safety Features

If you are a beginner or even a professional, for that matter, don’t invest in a treadmill that lacks crucial safety features. Such units may cause you injuries and might also hurt your motivation to work out ever again. 

Similar to most high-quality treadmills in the market, the JLL T350 treadmill has various safety features. For instance, it comes with an emergency safety key that stops the machine as soon as it detects a change in your running movement. 

The unit also has a smooth stop/start function, so you don’t have to struggle while controlling the machine according to your comfort. 

As mentioned earlier, the JLL T350 has sturdy handrails that can support your body at high speed. Besides, you can change the speed and incline level using the handrails only, saving yourself from all sorts of discomforts. 


JLL Fitness Limited is quite famous for providing a good warranty on its products. For instance, the brand offers a lifetime warranty on the T350 treadmill’s frame. This tenure reflects the high quality of this unit. 

Besides, there is a 2-year warranty on parts and labour and a 5-year warranty on the motor. 

When it comes to the brand’s customer service, there have been a few complaints regarding slow responses.
