Some users have noted that the auto shut-off feature may have a slight delay when the water level is low, which could cause concern for safety-conscious individuals.

In terms of maintenance, the design allows for easy cleaning, with a wide opening for access, but you will still need to regularly clean the tank to prevent mold or bacteria growth.
