I purchased the Breg Polar Wave with shoulder attachment a few weeks ago, and it is a solid cold/compression therapy device. You certainly get you money’s worth. I bought it because I need a total shoulder replacement and a going to push the surgery for several months. I was hoping that the Breg would help me along the way, and I have not been disappointed. I have had 2 previous shoulder surgeries, and I have rented Nice machines for the two week post-op period for both. In spite of the fact that I’m very satisfied with the Breg, I will still use a Nice machine after my next surgery. Let’s face it…the Nice machine is next level, and it has the price tag to show for it. I have been using the Breg with 4 ice bags and a hand full of cubes. The water stays cold for several hours. The compression is excellent. The shoulder pad does not fit quite as well as I’d like (specifically, there isn’t great coverage right on the top of my shoulder), but that could very well be a personal preference. This machine is easy to use, very portable, has a long power cord, and sufficient connection hose length. I highly recommend the Breg Polar Wave!
