This is a great machine, bought two, one in white for my mum and one in graphite for myself.
Both colours are very smart and modern looking. Machines are easy to use. Takes a tad longer to dry clothes perhaps due to the technology but it’s superbly efficient, which negates this in my opinion.
Not had a heat pump prior to this- it’s not loud but not as quiet as I perhaps expected. Makes a very high whistling noise as it dries, which I think is the mechanism. No great concerns.
Overall I think it’s a great machine so far with a brilliant guarantee.
