I don’t normally post reviews, but hope to prevent others from being out money as I am as a result. I purchased the exact same replacement pad for my cooling system I had, and confirmed with the current one I have that I ordered correctly. It leaked at first use, no user error. I reached out and tried to contact customer service about it and yet to receive a response and solution. I would not recommend this company, even though I love the cryocuff systems results.
