I have used this product once for a short period. Rechargeable cordless pelvic stretch air belt supervised by "Micaco," a charismatic figure in pelvic diet. [Product Overview] Miacoo's Hip stretch air belt provides a comfortable stretching experience. The specially designed air belt gently wraps around the waist, supporting stretching in a relaxed state. [Operability] The included remote control allows you to easily adjust the intensity and mode. You can enjoy stretching at your own pace, and it is suitable for a wide range of users, from beginners to advanced users. [Charging and Compatibility] A USB cable and power adapter are included, making it easy to charge. You can use it anywhere, allowing you to stretch easily even while traveling. It supports a slimmer body by "stretching," "lifting," and "tightening" the stiffened pelvic area! It employs a unique W air pump structure that comfortably pressurizes the pelvic area from 360 degrees in all directions with the power of air. By wrapping it around, it simultaneously achieves "stretching," "lifting," and "tightening."
