    Petite, but works amazing. Not as big as my palm. It is simple to set the temperature and maintains the temperature well. Heats the water up one degree in about 11 minutes and holds 78 in a 65 degree room easily. Suction cups are very strong and secure. To my surprise, I unplug for water changes and when plugged back in it remembers the prior setting.
