HP worldwide support rocks
I bought a refurbished iPAQ 4150 on eBay last August from the UK. I feared the worst when the speaker broke a few weeks ago. Would my refurbished iPAQ be covered by any guarantee? The Italian support form was broken (server error) so I had to explain my issue a few times via e-mail before I got a case ID and a phone number to call.
HP sent a UPS truck to pick up my iPAQ Thursday 17th just before lunch time. I got the fixed iPAQ back from Amsterdam Tuesday 22nd in the morning. Only 2 1/2 working days to get it fixed.
