This full-size mechanical keyboard is reduced to just £5
The Trust GXT 865 is actually a decent bit of kit too.
Mechanical keyboards can be pretty cheap these days, but I've not never seen one on sale for as little as £4.99 - especially not for a full-size RGB model available for a brand I've actually heard of before! That is indeed the case at GAME though, who are selling the Trust Gaming GXT 865 Asta for £4.99 plus another £4.99 in shipping - that's £20 less than this keyboard normally costs!
In terms of specs and features, the Trust GXT 865 looks solid but doesn't go beyond the core promise of a mechanical keyboard, delivering better customisability, key feel and long-term durability than a standard non-mechanical membrane keyboard. You do at least get a full-size UK layout, as mentioned, with an option of seven rainbow wave effects with optional brightness - including off.
You also benefit from n-key rollover, which means that the keyboard can recognise as many simultaneous inputs as there are keys on the keyboard - something that isn't possible even on gaming-grade membrane keyboards. The switches provided here are soft linear (red) models, so you get a relatively rapid key press with smooth action rather than bumpier (tactile) or clickier (clicky) switch alternatives.
Overall, an incredible value at this price and well worth considering!
