How it compares in Networking Devices

Across the 50 rated networking devices products we track, the typical score is 4.4 out of 5. This one sits at 4.3, which is in the bottom quarter of the category. That does not make it a bad buy, but there are better-rated alternatives on the same shelf, so it needs another reason to earn your money.

It carries 628 ratings against a category median of 10,792. That is a thin base by the standards of this category, so treat the score as provisional: a handful of extra reviews can still move it either way.

On price it sits in the upper third of a category running from £4.24 to £307, where the midpoint is about £24.97. Paying above the category norm needs a reason beyond the rating, because the score alone does not justify the gap here.
