Merrick Kunlun K4S

The quality of the product is average. After a few days of use, the bearing made an abnormal noise, which was later reported to the after-sales service and technical service. After confirmation, it is agreed to reissue the parts. One week after the delivery order number was sent out, it was a big black dragon (actually it was not sent at all). Later, I always hoped that after-sales could help solve the problem, but after another week, it still could not be solved! It's really helpless.

The volume can be said to be very large. I can see how many bricks I have taken up. The size is far beyond my imagination. The shock pad sent is more wobbly after it is put on. The effect is better if it is not put on. It is not particularly wobbly, but it is also a bit wobbly. My heart rate measurement function is bad. There is a problem when leaving the factory. I suspect that the factory quality inspection is not well done, although the master contacted the technical department to say that it was solved, But it has been delayed for a long time. The flywheel doesn't make much noise. Within the acceptable range, there is a slight noise when adding electronic resistance, but the duration is very short, which is harmless. Besides, the step distance and the user's weight can't be set, and there are still calories in the distance, which is laughable. I don't know whether this model is the best choice at this price. I can only say that if you want to buy a home computer, you'd better pay a higher budget. Don't buy such a ridiculous model

It is easy to install it. There are installation videos.
