Product conforms to the description, shipped by Amazon in time. I used 2-3 times and I already feel an effect on the legs, especially at traffic. My legs are less swollen and less "heavy". However, we must be diligent and use the device daily for 10-15 minutes in the morning hoping to see lasting effects. Contrary to what some people thought, it does not hurt, just put the device in minimum power and not too much pressure. Small negatives: lack of ergonomics at the grip and that the device should rest for 15 minutes after 15 minutes of use to prevent overheating.
