The two Impact systems achieve the highest VFM scores, chiefly because of their extremely low prices rather than any outstanding performance or specifications. This chart shows our assessment of the relative value for money for each of the products in this review.
Longer bars represent better value for money.
Products are sorted by price, with the highest price at the top. Where products have the same price, they are shown in alphabetical order. The resulting raw VFM scores are then made relative to the lowest-scoring product. To use the graph, first see which products fall within your chosen price range. The best value product within that range is then the one with the longest bar.
