I've been in and out of the saltwater/reef aquarium hobby for about a decade now. Everyone in that community is VERY weary of UPS and no one would even dream of using USPS for live shipments. FEDEX had been the only reliable shipping source with the best online tracking, and I cringe when I see anything else. That being said, my order from V4L came unscathed and on time.
most of the time, the V4L orders come perfect and fast. But never the less, there will always be an order that gets screwed somehow.
