I would never buy from Comet again ANYTHING!
I bought a DVD player from there, an expensive one in fact in 2001, it broke 3 months in and had been used only for 2 DVD's!
I went in and asked for an exchange since it had literally never been used - I went to university and never took it with me, so literally it had been turned on twice.
They said they would not replace only replair so it went off for 2 weeks and came back.
Still being at Uni again it was used maybe 3 more times before going wrong again.
Then bought my spin dryer which flooded after a month, again no replacement, it had to be "Tested" by the engineer, and he found nothing wrong with it, so would not do anything.
Thenmy Mum bought a mixer from there, took it home and found that it made a loud rattling sound when she first used it - like something was loose inside.
She was told that she could not have a refund the next day as it had been used, and if she wanted to exchange it she had to pay a 10 percent restocking fee!
She read them the law and got her money back!
There are so many complaints against Comet, its a terrible place to shop. Its a shame since they have some great products and a really good selection.
I browse only now, and try things in their store but buy elsewhere or online.
They are stupid since over the years I have spent a lot there, TV, XBOX's etc came from there but never again since I am scared if anything goes wrong the bad service I will get.
I buy from John Lewes or Amazon now, both have amazing returns polcies and good prices.
Also both ASDA and ARGOS are good to buy from with great customer services and returns policies.
You are right about UK consumer law, things to have several years on them, the good old EU gave us that, since they decreed that a washing machine / appliance should last a reasonable amount of time!
