I think it a good product, I have bought it for my mother and she is happy with taking it. my father also asked me to get some for him and I will do when I get some extra money. the dilevert was so good and the product arrived in the right time with avery safe box.
it does help me, my joints are much more flexible and the pain of my back has improved. the only drawback is the cost. For us pensioners (i am positive most of the purchasers are pensioners) it is quite costly.
It is rather amazing product and I have been taking it for a while now, for one year. I am happy with this product. I continue to use it and I highly recommend this product.
