Value for money
I have to say that for the price the performance of White Knight dryers can't be beaten, and that they seem to be better built than the low end competitors from Indesit and whatever. Would buy one in a heartbeat, if they only made a sensor model at a similar price point. (I know they make that A rated one but it sells for the same price as a Zanussi or Bosch sensor dryer so isn't really worth it).
Of course, they do that stupid reversing, but so does my £400 AEG condenser dryer & I always have to divide one bedlinen load in half if I want to use the dryer so that they don't ball up. So more expensive dryers don't really seem to do any better in terms of the balling up issue. Though Miele is supposed to have an anti-tangle feature which reverses the drum if it senses the load has balled/bundled up, I remain skeptical as they don't seem to receive a high rating for evenness in the Which? magazines. Those new Bosch dryers do look promising with their specially shaped paddles, but again they only go one way (claiming that the larger drum and uniquely shaped paddles prevent balling), so in terms of reversing it seems that the more expensive dryers aren't really anymore of an improvement.
