Our team on 3 continents has been working hard to get your the Photon of your dreams this spring. However we have run into a PCB issue that has caused a short delay in our first run. This means that delivery will now be at the end of April. We’re disappointed about this too, but we want to make sure we deliver a fantastic product that is great as it can be.
Keep in mind that we won’t charge your credit card for Photons until we ship, so if you don’t want to wait around for a few extra weeks, you can cancel anytime.
