Thoughts on the Quell Pain Relief Device. I have now been using the Quell pain relief device for 15 days. I definitely notice when I am not wearing it. Last week I was on the beach in Cape Cod with the in-laws for an afternoon, so I didnât put it on for fear of ugly tan lines. I crashed as soon as I got back to the hotel. My pain quieted within 20 minutes when I started wearing the Quell again.
