While this product may smell slightly of fish oil, which I?m not terribly keen on, but my eczema and itchy skin are very pleased after using it so I?m happy enough to keep using it. I have brought slippers that costed less than these that I have lasted longer. This is why one star was knocked off. Takes up hardly any space on my nightstand, which is very important to me and it sets my phone upright so I can see notifications without me constantly having to pick it up and place it back down on the exact spot to charge like other chargers. Nice quality but it needs to be bigger on the paws. 25jun17 update:changed rating from 4 star to 3 star. Much better quality for the same price. The foam in them is thick but so soft you might as well be walking on the floor. As expected Ted and will do the job The key lock system did not work, thus the end caps could not be installed.
