BEWARE - YOU WILL LIKELY LOSE YOUR MONEY
I nearly bought something then spotted it was ex-display. Many of the units are ex-display units - but they tuck the info away at the bottom of the "technical specification"?- its completely deceitful.
Worse still - this company are at risk of liquidation. Just Electricals is a trading name of 3 Pins direct - owned by one guy - Nazim Hussain. 3 Pins direct also trade as http://www.advanced-av.co.uk/ - check out their reviews on review centre and sitejabber - they take peoples money and dont send them the goods. Stay well clear or your likely lose your money.
3 Pins direct have been close to being struck from the register twice;-

If you lose your money sue them in the small claims court as quickly as possible while they are still in business. Also claim back from your credit card provider from section 75 of the Consumer Credit Act 1974.
