I’ve had the heater about 6 months and it’s working great. At first, I couldn’t figure out how to read the heater with my phone without removing it from the tank. Once I realized the proper locate to tap thru the glass, I’ve had no issues changing the temp thru the glass

I bought this a month ago and the heater busted in my tank at night and shocked all my fish tank! Read the reviews before buying! To change temp you have to take heater out of the tank. I’ve got to buy three different heaters for all my tanks now cause I don’t want this happening to any of them!!!! It won’t let me attach the picture to show

I bought this heater a week ago and it does have some quirks but overall performance is great. The heater linking with the app thing is not intuitive. Every single time you go to adjust something it asks you to scan it to make the adjustment, it would then make the adjustment but if you ever need to edit something you’ll have to pull it up to scan it really quick and put it back in. My thinking is I don’t need to adjustment the temp constantly so I just set the temp and left it. Now onto the good part: I have yet to have a heater keep my 10 gallon tank at a constant temperature until this heater. If you can overlook the quirkiness of the whole app linkage thing the performance of the heater is great and I would recommend to buy just know what you’re getting into first!

STAY AWAY FROM THIS PRODUCT! I should have read the reviews, and it’s not “contactless”, you literally have to remove it from the aquarium and hold your phone up to the heater, literally trying to find the right spot. So yeah, I just dropped a brand new iPhone 16 Max Pro into the aquarium. Packing it up in its original box as we speak so I can go return this junk that has no business being stocked in inventory. Read your customers reviews PETCO!!!!!!!

Do not buy this heater! To change the temperature you need to take it out of your tank and then it only works sometimes. Sicce needs to stick to pumps this heater is a waste of money!

I bought this heater roughly 4 months ago, just as another poster did, and it stopped working. My unit never could communicate with the phone app while installed in the tank in the *correct* orientation. This is the 2nd sicce product I've purchased, and both products failed out of nowhere within months of purchase. My tank is now at 70 degrees and falling and I have to wait to purchase a new one later today. Avoid if you care about your set up.

I bought this about 4 months ago and it has quit working I tried to recalibrate and everything and over night my tank went from 80 degrees down to 66 degrees thankfully my fish haven’t been affected but it could have been very bad. DO NOT BUY THIS PRODUCT ITS HORRIBLE!

This acquarium heater is ridiculously difficult to set up and program. It took my wife and I almost an hour to figure it out.
