I bought it directly from JLL since it was slightly cheaper. Excellent product and easy to assemble, sales department was very helpful and received a free matt with my order. The treadmill is sturdy and easy to fold.

This item was delivered quickly at a time convenient to myself, The 2 men were excellent, manoeuvring the large packages through a narrow hall and doors with care. It was straightforward to put together, the factory settings were perfect, and it is solid and robust and has worked perfectly to date. No complaints at all.

JLL S400. I could have bought this machine direct from JLL for a few £'s less but decided to buy through Amazon because they gave me that extra level of guarantee. From the outset JLL were very communicative with quick replies to emails. JLL went that extra mile to fit and to move the delivery date to suit me as I was very busy (Saturday morning delivery at no extra cost). Best off all JLL use 'Arrow XL' for the delivery (two man team). I received text messages from 'Arrow XL' the day before delivery and also right the way up to when they were just minutes away from my house. Delivery team placed the treadmill exactly where I was going to unpack it and set it up. Unpacking and setting up was very easy as it had been positioned where I wanted it. It took me less than 30 minutes on my own to assemble it. I did cheat however as I downloaded the user guide and assembly instructions from the JLL web site a few days earlier so I know exactly what to do when the time came. Plugged in stepped on and I was away, music playing through the on-board speakers. Only been using it since 5th December 2015 but overall I am really impressed with the performance and operation of my SLLS400. Use it daily for about two hours plus in a straight session. Will update this review in a couple of months time.
