Very courteous and helpful in dealing with my order error. A decent antenna delivered very quickly and I now have fm radio with a full strength signal.

I had a bit of a struggle with their online ordering, I managed to raise an order as "collection" rather than delivery by courier. However Blake's went out of their way to fix the problem. Otherwise their on-line service produces a good transaction trail.

Many thsnks
