I had mine delivered. From what I have seen is that its about 3 weeks from approval. Obviously it could be longer as they say 45 days to give them some leeway in case stock runs out. you should get a text/email when they are dispatched and yodel emailed me to say they would be delivered the following day.
Claimed mine on the Saturday 30th January and was validated immediately. Recieved them this past week so from claiming to arrival it was around 3 weeks.
