Despite there being a gremlin in their computer system my order still arrived in good time. Mike was really pleasant and helpful and he pulled out all the stops to ensure the order was dispatched. I think a sign of a good company is when something goes wrong they resolve the issue quickly. I would definitely recommend this company.
