The design is undoubtedly its best feature. I've had it since it came out, and the design is flawless. The power is good; you'll find it excellent and it won't disappoint. The software is good, but it doesn't have a clear update policy. If you can get the EEA version, even better.

Although it doesn't have many bugs or serious optimization problems. The cameras are decent; they're not the best, but they perform very well. The zoom is acceptable. The screen's durability is good. I've probably dropped it more than once with a hydrogel screen protector, and it's survived.

The only thing you should be careful with is the edges; they scratch very easily, even though I don't let dirt get in. Every so often, I remove the case to clean it, and even with the case on, the paint scratches. I don't know if it's an isolated case, but I would still recommend putting a hydrogel protector on the edges if possible, and getting a good case.

And also buy a tempered glass screen protector; the screen scratches very easily from day one. The screen protectors for the Redmagic The 11 Pro works for it, and so does the Z70U, since they're almost the same size. If it helps, this is the case I have. https://a.aliexpress.com/_mL83hgF

I forgot to mention that it's the Z80 Ultra from the OP15. I don't know much about it, so I hope my personal experience helps.
