"This heater is a bit more pricy than picking up an all in one canister but well worth the premium if you are into the more high tech aesthetic, or someone who already has other Chihiros products for your setup, such as a light."
"Been watching this from chihiros for a few months and finally pulled the trigger, this is an amazing heater, the ability to vary the wattage heating power is unmatched. The app is very easy to use and custom ability to limit power or jack that sucker to full 800 heating watts for rapid heat. If you have ever experienced a tankless hot water heater this is the same principle, only heats when it needs to and varys the watts as it does so. So impressed i got a second one for my 20 gallon."
"Great heater so far"
"Works great, adjustable wattage which is nice. Keep in mind unit is about 6” tall and needs to be vertical if you are space limited"
"The heater is quite bulky and big and unfortunately did not work for my situstion at all. Will have to return this item. Product came with very poor intrsuctions as well which was very dissapointing."
"Not a lengthy product in my opinion but a bit bulky but hey its Chihiros there about quality! Plus for my UNS 60S its going to be wonderful not have an in the tank heater. Plus this bad boy goes all the way up to 800watts when i want to upgrade tanks in the future. Great Purchase!"
"As expected"
"Great heater. Great features and app functions make it easy to customize the specs you want."
"Just got it installed, so far I really like it. Direct and to the point. Good for a variety of tank sizes, that’s great, so it can expand with my hobby. And greatly helped clean up some of the thank uglies (Cords). So far the only critique I have is the mounting, Realy, on a product this nice. Somebody dropped the ball. But I do realy like the heater. Would buy one again, and probably will soon."
"This is the future of heaters. The variable wattage maintains a stable temperature while ensuring there is still plenty of power available if needed. We haven't been running heat in the house yet, it is pretty chilly, and the temp on the tank is rock steady."
