One of the two machines ordered did not work properly - faulty mouse pad. Rather than dealing with the supplier - Save on Laptops - for the return we had to contact the manufacturer - Acer. This then means further problems re-registering the software for a replacement machine. OK you get what you pay for in this world, but it would be much better if either, or both, the manufacturer and seller actually tested machinery before they were dispatched. It takes hours to set up a new machine, and all of this time has been watsed by us trying to do it with a faulty machine, only to have to repeat the exercise all over again in a day or two when the replacement machine arrives. Frustrating - not all the fault of Save on Laptops, but more a general problem with the industry where buyers do not deal with the seller for faulty products - as is usual under the Sale/Supply of Goods Acts - but made to talk to the manufacturer. Acer were quick and helpful, but had the machine been properly checked before it was dispatched none of this waste of our time would have occured.
