I group controlling a burger and press supplementaires.Les 1st discs discs received were not the right size. there seems to be a recurrent problem. However, the service is impeccable, reclamation treated within 24 hours. I am told that compliant drives will be sent to me. 2-3 weeks without news, I reocntacte service representative who told me it's not normal and they will send me back discs. Shortly after, I receive in fact a new burger press. I recontacted service representative who told me that I keep the recue press and returns me the disks. Finally, although I get these discs in the correct format 1 to 2 weeks later. Finally, the product is ok, the order of preparation service leaves something to be desired but the service is very good. That does not leave me a negative review of the seller, but it would gain a better organize the preparation of orders.
