Good phone, plain box

Don't expect retail packaging — it arrives in their own recycled box. The phone itself though? Excellent, and the grade was honest.

Great value, tiny scuff

There's one faint mark on the frame exactly as the grade described. Screen is flawless. No complaints for the price.

Battery better than expected

Listed health was conservative — mine reads higher. Lasts all day easily. Impressed with the whole process.

First unit had an issue, replaced quickly

The speaker on my first device crackled. Support had a replacement shipped within the week under the warranty, so I'll bump this up if the new one holds.

Fine, but battery is just okay

Battery reads 84% — above the 80% they promise, but plan on charging by dinner if you're a heavy user. Otherwise exactly as described.
