I used BBK 9688.

9688 is very good now, although I am 9388! But 9688 has been upgraded now, and there is a digital materialization platform, which can do graphic calculation!

It used to be over 1600 (here in Xianyang, we don't know about other places), but now the price has dropped because of the new H 1 (still here).

Of course, other functions are still very complete! Learning and entertainment functions are very powerful. You can also download GBC simulator games, and of course, there are great cameras.

NP 1 100, Q2 has never been used, I don't know!
