I bought a laptop Acer Travelmate 4283WLMi off them on 19 Dec 2007, it worked only for the first two weeks.  
 
List of problems/issues:  
* 11 Mar 2008 - wrong battery shipped: doesn't fit the housing.  
* 09 Mar 2008 - noticed that time and date not retained, cooling fan constantly on (not normal for an Intel Duo Centrino). The battery is missing!.  
* 20 Feb 2008 After my official letter to have my money back of 02 Feb 2008 (suggested by Trading Standards) they raised a return number, repaired and shipped against my request of full refund.  
* 22 January 2008 - Laptop received from Repair Centre, still not working. The laptop beeps, the hard disk led flashes for a while, but the screen is off.  
* 15 January 2008 - Laptop received from Repair Centre, still not working. Display off. Using an external monitor, the laptop boots but then gets stuck. Acer support team arranged a collection.  
* 8 January 2008 - The laptop didn’t boot. Acer support team arranged a collection.  
* 1 January 2008 - First email sent through your website (by eMessage) for a problem with the Standby Mode: the laptop didn’t resume from Standby, reboot required.  
 
I'm stil waiting for their reply (and the battery!) and I will have to go to court at some point.  
 
The service has been very poor so far.  
Hope you read my review and think twice before dealing with them. If everything goes smoothly you will be probably fine, but if there's a mistake, then it is going to be very painful.
