The website was easy to navigate and locate the precise part for the Dell model. Ordering again was straight forward and both dispatch and delivery were very fast. The part appears to be high quality and at a good price.

Very impressed with my first order. The online pre-sales chat was very helpful, the order arrived next day as expected, and a follow up reply to request a VAT invoice was replied to and supplied very quickly. Would certainly consider ordering further parts from Black Cat
