    Black Cat couldn't have been more helpful from the moment I placed my order. Great communication with order shipping updates by email. I purchased a new keyboard for my Dell Latitude laptop and it arrived promptly and fitted perfectly. I will use Black Cat again when I need spares. Highly recommended.

    Next day delivery on my Dell battery, works perfectly and my laptop is now a laptop again instead of a plug-in PC! Having been ripped off on an “oem quality” battery in the past, it’s refreshing to get a genuine part, for a reasonable price, and from a uk business.

    I rang as was having difficulty finding the part I needed, it was easy to discuss my problem, the person took full responsibility and eventually the right part was located, which I then ordered online. this arrived on time and fitted perfectly. I would have no hesitation in recommending Black Cat for computer parts
