Super easy and professional communication with the team at Blake. And a great quality product.

I was pleased with the price and items received however the experience was somewhat marred by DX Couriers. Expecting 2 items in the shipment they only delivered 1 and tracking confirmed 1 of 2 scanned onto delivery vehicle. When I contacted DX they confirmed the second parcel was still in Sheffield at the collection depot. This meant I had to wait in a second day for the rest of the order to arrive.
