AI-generated summary
For £93.49 ex-VAT, this kind of 2-port DVI video splitter with audio is only really good value if you’re doing a very specific job: duplicating a single DVI source to two displays without getting clever. In day-to-day boardroom, training room, or reception setups, it’s the simplest way to keep both screens in sync—no switching, no HDMI adapters, no faff. The biggest practical win is reliability: splitters like this tend to “just work” as long as your source and displays are truly DVI-friendly and you don’t need advanced routing.
I’d be cautious if you’re modernising an environment where most kit is HDMI/DisplayPort. Also, “with audio” sounds convenient, but with DVI you’re often fighting compatibility—what you actually get out depends heavily on the way your source outputs audio and the way your monitors take it. If you need anything beyond mirroring (EDID management, long cable runs, different resolutions per screen, or frequent reconfiguration), this won’t be the tool you want. Buy it if you’ve got a straightforward DVI source and two matching destinations; skip it if your install is moving toward HDMI/DP or you expect “it’ll handle everything” behavior.
