Love this bowl set.  I got the largest size because I have labs.  The only thing to put together was attaching the legs and floor saver pads.  The legs just screw in and it also has adhesive dots to keep the bowls in place.  The boys have their water outside because they are so messy but, they share this bowl and there is plenty of room for them.  I also like that it sits up off the floor since they are bigger dogs.  I highly recommend this product, it is well made and very attractive.
