I've been getting a lot of questions about when the sentry controllers and sentry shields will be back in stock. For those who haven't heard, here's the scoop:
The last batch of standalone controllers came in with a small defect, which made them unusable. In addition, PCB production is still a little backed up from the Chinese New Year holiday week. Between those two factors and the high demand, the controllers have been a little scarce lately. The best estimate on the next batch is March 25, or thereabouts. When the next batch arrives, orders will be filled on a first-come first-served basis. That means backorders will ship first, then any remaining stock will be for sale on the website.
As for shields, they will also be arriving around March 25. There should be plenty to go around.
