I have to admit that my dealings with Vax have been different to those mentioned below. Motor in first motorised bush head melted a pin and it came out of the side, that upgraded it to a better pet hair version no problem. First battery died, again no problem at getting a free replacement (had a spare one luckily) the both of my batteries failed (apparently the batteries are rubbish) and once again replaced without fuss. If you buy directly from Vax the Warranty is activated before you receive it. I have always found customer service staff very polite and helpful.
