I have a monsoon system and they are actually really good and simple to set up. They re-designed it so make sure its the new & improved one (theres a red sticker on the box that says so) and leave the cap off the container so the water can evaporate out into the air and not inside the container and on to the control box that has all the motors in it as they have been known to get water damage that way (may have been the old design but better safe than sorry!)
As for milks go they don't need misting regularly and like to bask (i wouldnt go higher than 90f for a basking spot) so they don't need high humidity and a light misting before the lights go off at night is sufficient. Also these guys need UVB 10%. Atleast 5% UVB if you don't trust me lol. They are out in the high up in the trees in the sunlight in the wild unlike other frogs that hide under leaves. They can be very jumpy so wouldn't recommend young kids holding them. Mine are used to being handled and occasionally one gets away lol.
