What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I have 3 of these heaters in various sizes and they all work great. The suction cups aren't as sticky after a few months but thats what happens to all suction cups unfortunately. The heater is brilliant and its great knowing it has a safety cut off and detects when out of water.. highly recommend”
Verified purchase“Ordered it without reading the bad reviews on it. Wasn't expecting much from after that. NOTHING wrong with it, it keeps water at constant temperature & fully adjustable temperature range.”
