• The deal: The Asus ZenScreen MB166C is £73 (was £94) at Amazon.

Why we recommend it
We've had good experiences testing out previous Asus portable monitors in the ZenScreen line, but this is one of the more practical models. This ZenScreen is light enough to carry alongside a laptop. Its 15.6-inch panel gives you a lot more working space and it can automatically switch between landscape and portrait orientations. There's a tripod socket on the back if you don't want to use the included foldable sleeve. The 178-degree viewing angles should also make positioning it easier when you're working in a cramped space.

Should you buy it?
✅ Buy the ZenScreen MB166C if...
You regularly work away from a permanent desk and miss having the additional screen space of a desktop setup. It's particularly useful for keeping email, documents or reference material on a second display while working on your laptop.
❌ Skip the ZenScreen MB166C if...
Your laptop doesn't support USB-C connectivity, or you're a creative professional, as the 60Hz refresh rate and 250-nit brightness are geared more toward productivity and general use.
