I got my first order from them a couple days ago. Everything went very smoothly, no complaints at all.
Ordering online was easy, they sent confirmation emails with a fedex tracking number, they called me 2 hours after the rats arrived to confirm arrival. The rodents themselves look really nice too - since they're not vacuum sealed the rats don't get frozen into random shapes/positions with tails and legs intertwined with one another. No blood coming from their mouths etc... The packing job was impressive - cardboard box, then a styrofoam box, then an insulated "bubble wrap" bag that contains the bags of rodents and the bag of dry-ice.
Very nice experience overall - I will be ordering from them again.
