Advantages and Disadvantages…

Pros for the JLL T350:

  • You get great warranty protection cover with 5 years on the motor and 2 years for parts and labour which is superior to many other brands
  • There is the USB port, Bluetooth connection and loud speakers which again are not always available from premium treadmill brands
  • You can customise the first 3 programs to your own preferences or work through the remaining 17 pre-set programmes for a good varied workout session routine – different programmes for different days of the week
  • The deck size is plenty big enough for longer strides coming in at 41cm wide by 121cm long
  • Lower priced treadmills don’t always offer inclines but you get 20 different inclines included with this JLL treadmill
  • The power of the motor is strong and durable and you have the ability to run at faster speeds up to 18 km per hour where many other treadmills have a max speed of 15 or 16 km per hour
  • For added safety, it has the hydraulic soft drop folding mechanism and the roller wheels to support mobility from one room to the next
  • Inclines can be done automatically without you having to adjust them manually when you choose specific pre-set programmes

Cons for the JLL T350:

  • This treadmill is designed only for home use – it cannot be used in any commercial or business like settings
  • There are no display setting for miles per hour so you are limited to km per hour only
  • Isolated cases have been seen where there was issues with the motor alignment which resulted in unexpected loud noises.
  • Customer service care for any potential issues that may arise seem to be quite poor – especially when it comes to any technical or structural faults or belt issues
  • Some of the structural frame parts seems to be a little flimsy and could be sturdier, especially when using the handlebars either side for balance support
  • Regular ongoing maintenance work and belt tightening adjusting is required on your end so make sure to read the manual and follow the steps required.
  • Even though the deck is 41cm wide, it is still slightly narrower than what we would like (wider decks are outlined below)
  • While we didn’t experience any issues with a noisy belt, there has been reports of others who had experienced it which should be pointed out - plus belt slippages after oiling has been reported

After completing this review for the JLL T350 Treadmill, we hope the information here can help you out in some small way and perhaps point you in the right direction on what route you should take. Some of the older issues seems to be rectified but when it comes to a foldable Treadmill, this certainly gives you great flexibility in a small compact size to keep it as small as possible when folded up after use.

Time will tell how it performs over the next few months but starting off anyway, we were certainly impressed with the overall package, features and entertainment support and having the long warranty in the background certainly goes a long way to protect you and your investment in the future. Like any other machine that gets a pounding so to speak (by your feet), you need to make sure to keep the machine fully maintained and take care to read the manual especially when it comes to looking after the belt and the running deck surface.
