Fast delivery, a brilliant price and great customer services. Couldn't ask for a better service. The tablets are brilliant too. My 13 year old staff suffers from osteoarthritis and these help him through the day. Definitely recommended

Our 12.5 year old German Shorthaired Pointer appears to be doing well on them as far as his stiff joints are concerned, he's a little stiff towards the end of the day, however in comparison to how he was prior to the Onisor, he's now doing great and life doesn't appear to slow him down any. Still very much a typically crazy, very much loved GSP family member.
