Some users may find the 200-watt capacity limiting for larger tanks, as it is only suitable for those up to 65 gallons. While the heater comes with a respectable 5-year warranty, it's essential to note that it doesn’t cover damage due to misuse, which might be a concern for first-time aquarium owners. Additionally, as a glass heater, care must be taken to prevent breakage during handling or cleaning.
