I bought a refurbished Vax 2 pwr directly from Vax. The battery soon failed. They sent another (after spending a long time hunting for an email) . The battery soon failed again. They refused to replace it as the original warranty on the machine, (not the battery) ran out by around a month. They refused to replace the battery. I had to write to them as they would answer numerous emails over that end month. They refused to send another and I haven't had a response again after asking to replace the battery as a gesture of goodwill as two batteries should not fail in 12 months and they didn't respond to my previous emails. They make it really difficult for you to contact them. ( see website) I have had no apology. Still waiting for a response about the battery. If they don't respond to this then you know not to buy from them
