Sorry need more details than that. Which retailers? Wheres the I got my dongle thread with pics? I don't think a lot of people have them in their hands yet.
Also for speed Modchipsdirect being based in USA is a bad option. If you bought from a Chinese company they mail it to you direct, it goes through customs fast because it is a small little package.
With a USA warehouse (like modchips direct) they have to wait for the shipment from china just as long as if you ordered it directly. It is a large shipment of electronics which causes additional customs delays. Then they have to repackage, put on shipping labels and mail it out. This is all slow and takes time.
6 months from now when everyone has these sitting in their warehouse ordering from modchips direct would be the best as you get it in a few days where ordering from China can take a week or two.
