It is an old model or a product that we can no longer order at the manufacturer.
Still have not received this product after 2 weeks and they ask me for a review?? Don’t order from here, it’s a joke, I out over £400 for 2 pairs and no update from customer service.
A bit of a joke, I ordered this product over 2 weeks ago snd still have not received & no news on getting any refund. They ask me for a review even before receiving it. Sad to say font order from here.
