Put us to the test

Our Test Labs compare features and prices on a range of products. Try Which? to unlock our reviews. You'll instantly be able to compare our test scores, so you can make sure you don't get stuck with a Don't Buy.

We surveyed thousands of Which? members to reveal the most reliable computing brands in every price bracket. To do this, we asked respondents specific questions such as whether a fault occurred with their PC, how long it was before the fault was detected, and if they were able to successfully exchange their faulty all-in-one PC with the vendor - or have it repaired.

Our overall Customer Score is based on a combination of how satisfied owners are with their product and how likely they are to recommend it to a friend.

All-in-one PC brands rated
Brand Average test score Reliability rating Customer score Verdict
75% 88% The best all-in-one brand across the board in our survey, and by some margin. It's a big brand with big expectations, and our readers certainly don't feel disappointed.
61% 71% Our tests find PCs from this brand to be fairly middling, but the good news is that if you do buy one, it should last you reliably.
64% 72% Consistent across the board, this brand makes respectable AIOs, and customers find them to be reliable, too. It's not up there with our highest-rated brand, but it's passable.
65% 68% Computers from this brand score reasonably well in our test lab, although, at the time of writing, we're yet to uncover a Best Buy. Even so, the results of our survey suggest that this brand produces plenty of reliable machines.
67% 64% Capable of both Best Buys and mediocre models, this brand is something of a mixed bag, and you'll definitely want to read our reviews before taking the plunge.
