We post updates in the news section on our homepage.
Here is an excerpt from the latest update:
We expect the first packages will depart at the end of July / beginning of August. The currently pre-ordered flashguns can be expected for delivery throughout August and September.
Please note that our warning regarding the shipping date for pre-orders still stands: "Delivery times may change due to production delays or product improvements. If you are planning a diving trip with the new Retra Flash at the time of the estimated delivery date we strongly advise against pre-ordering! There is no guarantee you will receive the product on time. Your pre-order may be fully refunded at any time. Currency conversion changes will not be compensated in the event of a refund."
More updates will follow in the coming months as we edge ever closer to sending out the new products. Right now we are super busy with the pre-production runs.
