    Well made and very solid product. Arrived on-time, but despite measuring my wrist it was too small to get on my arm, so I returned it for a larger size. When the replacement arrived I had only worn it for a couple of hours and I had green marks all over my wrist (it does warn you about this in the leaflet). I contacted Bioflow who were VERY helpful, and exchanged it for a matt stainless steel one, which is great. Nice company to deal with and a great product.

    A really well bracelet and looks great. I get a green mark on my wrist from the copper but it causes me no concern. Bioflow was recommended by a friend who like me has tennis elbow. I still get some discomfort from the tennis elbow but nowhere near the level I was getting prior to wearing my bracelet

    I bought my Bioflow because a friend recommended the product. I feel as though I am sleeping & feeling better now with the aid of my new Bioflow & would recommend & have recommended this product.

    The bracelet is stylish and comfortable to wear. A number of friends had recommended a copper bracelet with magnets to ease knee and hip pain (arthritis). I have been wearing it for about a month now and have yet to feel any benefit. However, I have been told that is not an instant panacea so shall be patient and see what happens.

    I bought this bracelet on the recommendation of my GP who said that some of his patients had found it effective. I have low back pain. Sadly, despite wearing it day and night for several weeks, I have not had any relief from my symptoms. Looks nice though!

    The bracelet is comfortable and stylish. I have been wearing it for a few weeks now and am not yet sure if there is any benefit. Perhaps after a couple of months I will make another review.

    Early Christmas present. Very stylish and fits well. It may be too soon, but husband has said it has not helped as of yet.
