I ordered a refurbished iPhone 4s as a spare phone when travelling. I took it to Japan and it didn't work kept shutting down. They replaced the battery and the next time I needed the phone - now - it still shuts down randomly. Brought it to the Apple Store. They say the battery is faulty.

I'm so disappointed with this company. Went with them because of the reviews but am again let down while travelling so stuck without a phone to use with a local sim and paying roaming charges again. This adventure has cost me a lot now.

So, I wouldn't recommend them.
