I have an Incuview. The plastic screen is a bit flimsy and if a chick is sitting in just the right position and all the water trays are full, the chick will be soaked and could drown. I found this out when I accidentally put in too much water to raise the humidity. I had my eggs on a paper towel to help the chicks with traction and the paper towel ended up soaked because the weight of the egg caused the screen to sag just a bit.
Downing is a possibility if you aren't careful about how full those trays get.
