Product Name: POWERbreathe Plus Respiratory Muscle (Inspiratory Muscle) Training This is the Plus model of POWERbreathe. It works without any problems. It has been cleaned with chlorine before listing. I bought it intending to use it for vocal training, but I didn't use it much, so I'm selling it. Everything in the photos is included. There are no issues with the operation, but there are some minor scratches. Please refrain from bidding if you are concerned about this.
