The machine itself is sturdy and has a professional feel to it, which is a plus. After using it for a few weeks I've noticed some minor improvements in the firmness of my skin, but the cellulite reduction is not as significant as I had hoped. First, the device is quite time-consuming to use. Each session takes up a good chunk of time, and you need to use it consistently to see any results. This is something to consider if you have a busy schedule. Second, I found the instructions provided to be somewhat lacking. While the basic operation of the machine is straightforward, I felt a bit lost when it came to using all the different features. I ended up having to look up additional information online, which was a bit of a hassle. Overall, it's a decent product, but I think there's room for improvement. If you're considering purchasing it, be prepared to invest a significant amount of time and be patient with the results.
