I do not know about a health guarantee, I know they don't on live mice (say one died on the way home before you got to feed your snake) which is why I buy live from a different source where they do have returns on live food... as for their rep, I am also not sure. I have only ever bought food from them and tongs. That's it. They don't often have different morph combinations. Usually they have simple morphs like pastels, lessers and pieds so not very often am I interested in what they have. They are not breeders as far as I know. They buy from breeders and then resell them. They have more other types of reptiles such as bearded dragons (which an employee does breed for them). geckos and frogs and such. Corn snakes, boas and ball pythons are the only snakes they sell and they have a very small section of them. Usually their BPs have stuck sheds which is another reason I have never really been interested. Customer service... well, yes and no. They will not come to you but once you get their attention, they help you and usually have good advice. They have a 3 1/2 out of 5 review on google. Their cages are for the most part clean.
