They claim 100% satisfaction or your money back, they also claim to be able to unlock iPhone 6 on iOS 8. I'm on iOS 8.2, not a problem they said so I paid for and downloaded their software. When it didn't work I contacted them, they told me to try it again in 48 hours. It still didn't work so I asked for my money back but they talked me into buying a chip that you place under your sim and promised it would work. When the device came it didn't work and on the packaging it says it's for iPhone 5 on ios7. I've asked again and again for my money back until they stopped responding to my emails. I have now gone to my bank and opened a dispute with this company. Ive since found out that the only way to unlock the iPhone 6 is by a full factory unlock. Their website is lying they can't unlock the iPhone 6. Avoid this site at all costs they are lying crooks.
