Finally, something for my back knots!
Bottom line: This cleverly designed device WORKS! I see a licensed massage therapist on a regular basis, but my stress at work & from the computer continues to knot my muscles up at a faster rate than my massage therapist can get rid of them. The only way my sinuses drain is when my knots get worked on, so I am only "clear" after a massage & for about a week later.  Now, I finally can have clear sinuses every day! I have been using this daily since it arrived in the mail last week and my sinuses are clear! If you are on the border of whether or not to purchase this, cause if you are like me, you think the price of $30 for a molded piece of plastic is too high, which it is, but with all the positive reviews (and I am so glad people took the time to review since that is what helped me make the decision to buy it)I figured sinus relief for a one time shot of $30 has got to be worth it. This device is more incredible than I ever imagained. I am in my mid forties and have been suffering from back knots for about 5 years..I wish I had known about this a long time ago.  It allows you to be in complete control, you use whatever pressure you want and work out any area you want. One end has a larger opening than the other, so it allows you to work further down your back. The shorter S end allows you to easily work your upper back. This device is so easy to use either sitting or laying down. I am very glad I purchased this and have shown others...now they want to buy one too!
