The ladder post I posted before ran away and can't be used, so I'll resend it now.
This wall climbing tool is OK. Although its speed is worse than the appgo I recommended before, its stability is good. Both ends can be used. However, the wall climbing tool is full of garbage on the PC end. There are few lines that can be connected ...... As for the package, don't buy it for one month. The monthly price for one year is only about 14rmb.
