I've used different companies for computer parts and water cooling stuff and watercoolingshop.co.uk has to be one of the better companies to deal with. I ordered something wrong and ended up returning the item without a problem. Fast customer service if you have questions. Fast dispatching orders.
Totally recommend if you need water cooling parts for your pc.
Ordered watercooling parts, made a mistke by ordering barbs that were the wrong size for the hose, recieved a call from the team to ask if i had ordered a different size intentionally. Incredibly polite, very fast turnaround times, great value for money. Have ordered from Thewatercoolingshop & its sister company C&CCentral numerous times, and have never once had even the smallest of complaints. Customer service level = Shining example.
