I can not comment on the other reviewer's negative comments as I have had no problems with mine and have not needed any form of customer service. I have had one of these dryers for the last 6 years and use it regularly. It is compact, very simple to use and very reliable. My White Knight Dryer also says it was made in Britain (which does not always inspire confidence). To be honest, I did not expect to still be using it today as it was so cheap. It has easily paid for itself.
Obviously a half-sized dryer is not of great use to families but I can heartily recommend it to couples, single people, students, people in flats or where space is a premium. It will also fit into practically any car and it is light enough that it can be carried by one (strong-ish) person.
I would not hesitate to buy another, should mine break down any time soon.
(They are available more cheaply elsewhere, if you look around - mine was from Co-Op Electrical)
