Purchased a Dyson hair care system. It didnt work, took it to Dyson for repair. They advised the item was counterfeit. When I tried to contact the seller, Mercari blocks contact after 3 days. Called them, they say nothing can be done as it is after 3 days. Repeated contact, explaining that the seller is misrepresenting what they are selling, that this was counterfeit only led to the same answer. This is insane, they shelter a criminal with a policy that only hurts the buyer. Plenty of other places to buy in a much safer environment. Stay away
