At the end of 20 14, I bought an M7 treadmill for 5000 yuan. After only half a year, I can't jump. After contacting sales, I tried to avoid it until the machine was out of warranty and I had to spend my own money to replace the parts. Moreover, their master repaired it like this: remotely diagnose which part is broken, and will directly tell you to buy a new one and replace it. If the problem is not solved, then continue to replace the next part. This kind of big guy is very important after sale. Don't buy those without after-sales maintenance in the local area. I will definitely regret it. Anyway, after I bought this high-end atmospheric treadmill, there are only two words left.
