DO NOT BUY anything from JLL Fitnes. Selling Faulty Products, and refuse the Warranty!!! Bought an S300 Treadmill. Instruction was hard to follow, lots of steps are missing. Out of the box the treadmill had a lots of scratch and chip damage. I ordered a new one but i think I got the showroom one :( The build in speaker sound like an old radio from the 60's. On the screen the programs info only: p01...p02...p11... not show any info what the program is. Programs info only in the instruction manual. Durring the program can't check the calorie or heart rate, works only on quick start. The Hearth rate shows only 78, its never change! Not count your Hearth rate 2nd day: the handlebar slow down button stuck (possibly broken inside), not worked any other button pressed it 20 times then get back to normal. Customer service told: "The buttons are stick unfortunately, so you will have to pop them out." Thanks During the excersize continiously got an electric shock. There is a rubber mat under the treadmill, and using non synthetic clothes but can't get rid of this electric shocks. The Screen get damaged from this electric shocks, but the Customer service ignored my emails. DO NOT BUY IT, there is no warranty
