On the eve of the system’s release, tech reviewers across the internet are sharing their thoughts on the new ROG Xbox Ally, Microsoft’s long-anticipated foray into the portable gaming market.

While designed specifically for Amazon's Luna cloud gaming service, it's compatible with other platforms, and it's back down to an all-time low price ahead of Amazon's Prime Big Deal Days event.

Amazon extended its Prime Day deals on Xbox wireless controllers, but here’s the catch: most colors sold out fast or bounced back to their original prices. The Velocity Green version is the exception. It’s currently the best-seller in Xbox controllers on Amazon, still in stock, and sitting at a record low of $49 instead of $69.

Speaking of customization, it felt strange that one of Scuf's USPs wasn't utilized in the Valor Pro. One of the reasons people are attracted to this brand's controllers is that you can customize every inch of color and get something that's truly yours.

In the US, the slightly newer model, the Thrustmaster eSwap X2 controller, is down a near-record-low price of $139.99 at Amazon (was $179.99) - it's the lowest price since March so represents great value.
