Unlocked my Rogers Samsung Galaxy S5 without issues - was skeptical with the company as I hadn't heard of them, but paid using Paypal which helped relieve some concern. The next day I received the unlock code (they said to expect it at least 24hrs later), worked on first try, and phone is unlocked. Will use them again the future.
Tip for consumers: If concerned, use Paypal, but you won't need their protection!
