I recently received my part of a trade from Arthroverts. Everything arrived safely, and was healthy.
Minor delays in shipping came from concern for the animals in transit, and are a sign of a seller that cares.
Like others have noted above, packing was fantastic. It's surprising how common it is for live animals to be shipped with minimal packing material, unsecured container lids, etc. None of that was the case here, and a good amount substrate was included to ensure shock absorption and provide food/moisture if the journey was longer than anticipated.
