Review: Seems decent quality and works more than acceptably well given the reasonable price - Fairly quiet and feels nice to type on after years of comparatively clunky Dell keyboards which were also far noisier. The mouse is reasonably accurate especially considering the price and overall I’m very pleased- the only downside is in low light the keys are hard to read as the lettering seems slightly metallic and it reflects the light badly.
Review: Good Product - Good keyboard and mouse, easy set up. So far so good. Knocking off 1 star as advertised as white but what I received is light grey. It doesn't matter to me but the listing needs correcting

### ⭐⭐⭐⭐⭐ Seems decent quality and works more than acceptably well given the reasonable price
*by J***Y on 18 November 2025*

Fairly quiet and feels nice to type on after years of comparatively clunky Dell keyboards which were also far noisier. The mouse is reasonably accurate especially considering the price and overall I’m very pleased- the only downside is in low light the keys are hard to read as the lettering seems slightly metallic and it reflects the light badly.

### ⭐⭐⭐⭐ Good Product
*by S***6 on 8 January 2026*

Good keyboard and mouse, easy set up. So far so good. Knocking off 1 star as advertised as white but what I received is light grey. It doesn't matter to me but the listing needs correcting

### ⭐⭐⭐⭐⭐ Brilliant, affordable.
*by M***A on 12 March 2025*

Brilliant pair, well-made. I love the feel of both keyboard and mouse. Delivered on time, neatly packaged with batteries included. Only one USB Bluetooth dongle is needed for both; connection is seamless. I recommend them.
