Very pleased with this purchase! I was surprised and thrilled to see that it is rechargeable!! So you can use it at your desk, during the workday, and not have to mess with being within a distance of a plug, or the added cords! Feels great, and runs pretty quiet. You can hear it pump in the air and release, but if you put the control in your chair, or on the floor, it can’t be heard if you’re on the phone. Several patterns of pressure, and pressure levels... the lowest level is all that I’ve used... and it’s been enough!! Seems like it will help with circulation during my 10 hours, sit down, workday. Highly recommend!
