I have a stubborn knot between my shoulder blades and the first use provided immediate relief! I can't wait to see how it works on other stubborn injuries and scared tissue.
It doesn't matter which setting speed it's on, the gun will go from full vibration and power to randomly dying down to to very slow vibration and then back to half power, then full again. This has caused more injuries then has helped. I wish I could add a video to showcase this flaw.
Love the quality and feel of this massage gun. I had a cheaper brand one before I bought this one, and there's no comparison. This thing weighs something, is bigger than expected, and has a nice professional feel or rhythm to it!
