Works well, good value...
I bought my WP009 a few months ago. I did encounter a slight issue with the belt misaligning after some use, but customer service was quick to respond and sent me a helpful video guide on how to adjust the belt. I followed the instructions in the video, and the belt was perfectly aligned afterward. I’ve noticed a tiny bit of misalignment after 1-2 months of frequent use, but it’s very minor and something I can easily accept. Given how often I use the treadmill, it's not surprising, and overall, it’s still working great!
