Three weeks ago, we launched the Quarto and a partnered with Vescent who is our exclusive US distributor (press release) and already we have sold out of our initial inventory. This is exciting as early sales were much higher than expected, but unfortunately it means that we cannot ship from stock currently and any new orders will be delayed. We are working to get more Quartos made as soon as possible, but given the global chip shortage, this will take longer than we'd like. For the latest update on availability and lead-time, please contact us.
