So far it serves my purpose. But i observed some occasional hangups of the scope during acquisition (need reboot to recover from hangups). I now upgrade it to latest firmware and as of this time, i don't observed any hangups. The build in function and arbitrary generator are also ok, but if your into audio work and you need a low distortion signal generator..then this equipment is not suitable for you.
I suggest get a Siglent and a dedicated Function Gen
Hantek support is slow and very much limited..
