Bought 7 Items from this site, having problems with 5 of them.
Two arrived and were OK - Just
Three arrived and were REALLY POOR shoddy fakes
Two never arrived and the sellers have simply disappeared off the face of the earth - with my money
Fed up trying to get any sense from Ioffer, the site is poor, difficult to use and flaky.
iOffer do no more than pay lip service to complaints and bounce you off to your credit card insurance, neglecting their own responsibilities to check out the legitamacy of the sellers at the other end of the chain.
I have traded on EBay for over 10 years and have completed 1, 000s of trades without a single difficulty, so it can be done if you are interested enough, IOffer just aren't.
I suggest you avoid this site and use EBay
