Nice lantern and it was fairly easy to screw into the soil but there are two things that could be better:
1.  It would be a lot easier to change the light intensity and duration if there were a door in the clear part that could be opened.  As it is now, in order to change the setting you need to unscrew the top lid in order to access the switch.
2.  It would be nice if the company offered wedges or heavy duty shims to place under the base in the event that the soil is not completely even, which it rarely is.
