I would avoid buying from www.r4i.co.uk I bought 3 cards for £60. all stopped working after 2 days. My friend is very knowledgeble with the kernels, updates etc. These cards are mixed with fake cards. the after care support was disgusting. I was asked to make additional payments to firstname.lastname@example.org.. aol for a big site?? very dodgy. I would avoid at all cost..
