O2 X2/X3 DONT DO IT!!!

I bought a brand new o2 x2 phone for myself from a local o2 shop, within a couple of months the phone completely broke, it wouldnt work at all, it wasnt worth the money at all. My friend who happens to work in one of the o2 mobile phone shops has recently told me that they are very badly made.
same goes for the o2 x3!!!
If my brand new x2 phone didnt work just think what your buying on here! at least from a shop there a guarantee and the option for insurance on it!
IF YOU NEED TO BUY AN X2 PHONE MAKE SURE ITS INSURED!!!!!!
