James - 5 out of 5 Reviewed on feefo.com in the United Kingdom on 14 October 2025
The product is pricey, but well worth the money. If you flip between many games on the Series X, it’s definitely worth it. Don’t have much time to play these days, so try and play everything I can, so I like to have as many games as readily available as I can.
I’d also like to compliment the fantastic service I received from this company. When I accidentally placed my order incorrectly, I submitted a support ticket at around 2 am, and I was very surprised to receive such a speedy response first thing later that morning.
My misplaced order was immediately cancelled by the company, and I placed another one with next day delivery added, which I didn’t actually expect to come on time, as most companies promised next day delivery, but they never actually are able to provide it.
I felt very looked after and cared for, and they went above and beyond to help me.
Would definitely recommend - 10/10, excellent service.
