Where to start … delivery was over a week late, with no phone call in advance confirming delivery slot despite this being promised - luckily we were home. Delivery driver scratched my car walking up against it and neither JLL Fitness nor the courier have made any attempt to address this. On 3rd or 4th use of the treadmill it started tripping the mains RCD - have tried everything including a dedicated mains circuit and proved the treadmill to be at fault. JLL Fitness have blocked me on Twitter at the mention of my dissatisfaction of having my property damaged, and have now stopped responding to all emails trying to arrange refund and collection of the defective treadmill. Worst consumer experience I have ever had. Due to lack of response I will now probably need to take legal action just to get my money back and have the faulty device collected! Would avoid at all costs, incredibly unprofessional company to deal with.
