Delivery speed is slow. More than week and nothing happens. If your process is slow you should give clear indication about that fact in confirmation. Setting expectation level is good idea.

Totally happy with the whole process of buying. Clear and easy to use web site and a seamless transition to the payment site. Contacted customer service before purchase, quick and clear reply.

am very pleased with the whole process. You have to watch the transport package, the parcel has got into my hands in poor condition TUNE PEDAL outside the box and the bag torn.

When I ordered, there was no stock for the particular car I owned. I waited one week for the stock but had to write in to check what was the status. However, I must say the response was good.
