I would like to point out that Which scores on many items that are fairly new on the market and not used every day for several months. They may review the same item 2 - 3 years later, but by that time it is too late as you have already bought the item.Survey's are almost always the averaged results from a sample, and as we should all realise when you see an "average" there must be some variation in the individual responses. If you make a purchase based on a survey result you are just as much risk of receiving a product or service which is better or worse than the average shown in the conclusions.
Where I would disagree with the comments about "Which?" reviews is that the Consumers Association has a long history and track record of professionally gathering evidence and their reviews usually take into account not just the average result, but also the spread or consistency of results.
However even when a product or service is highly recommended by "Which?", it is only a better probability of satisfactory performance compared to other brands. It certainly isn't a guarantee, and of course a failure may not be caused by the manufacturer, it could be transit, it could be fitting, or it might even be the owner buying the wrong product or using it incorrectly.
Also many Which reviews understandably are not based on a collective widespread consumer review input where the item is new to the market, but rather by their own team using their own tests. In our case on at least two different occasions has definitely been a manufacturing failure!
However Which reviews are a good starting point and reading their views carefully you can determine whether the item is suitable for your needs even if it has a lower score.
