As described, well made, easy to use, great for muscle pain, circulation problems or just to relax your legs, no need to keep velcro tight as the airflow will be different for each type of massage so you're better to keep it a bit loose when applying them on the legs. 1 charge lasts through 6-10 massages depending on which massages you use each time, the strength, and whether heat is also used or not(at least that's what i found with heat used each time at level 2, strength 2, kneading& lifting massages used each time). They are very comfortable to wear... my mother-in-law and i have been using them&after daily treatments we've both already seen improvement in varicose& spider veins as well as less pain and swelling when walking around during the day. Highly recommend!
