I got my beard from Dachiu.. I've had him for 6 weeks now and he's growing like a fiend with no issues.
I just started up my dub colony.. But I've been purchasing from kfcfeeders out of Georgia. They're legit, fast, and produce healthy bugs.
I did a purchase from dubideli about a month ago, and will never purchase from them again. 25 % of both the feeders and adults died within 4 days. There were also a couple of fleas in the batch that I luckily managed to kill before they escaped from my garage into the house. Do not purchase from them.
