I got this for my 10 gallon betta tank. Its set to 80, but in the winter it usually hovers around 75. I love that I dont have to worry about it causing problems when I do my water changes, and that alone is worth keeping this around.

I have the 50w and for a small 8 gallon. It’s constantly off by 3 degrees and its place correctly with the flow. I can’t say I trust this.

It’s perfectly sized and the temp does stay within range easily. Only complaint is the display is often immaculate of actual water temp (mine varies by .8 degrees) but it doesn’t matter that severely overall quality purchase for the price

Nothing else to say, I wish there was a refund for it. This product towards me as a customer is a complete scam. It failed me so soon and now all it does is tell temperature and send a signal to a non-functioning heating element. I feel like I paid 10 times the price of a normal thermometer that also costs electricity and a power outlet to run. If this isn't a scam and I ever get refunded in full for the product and compensated for the product, then you'll know what you are buying because I will be updating the review. Until then, the product has nothing impressive as an aquarium heater, to fail without misuse on my part or anything of the sort is downright theft.

Heater has held up well for a couple of months in my 8gallon tank without issue - accurate heating - really good size - the cord is a bit short - the packaging was wet for some reason (seller kindly offered refund) - overall, great nano tank heater

UPDATE: Customer service reached out and was very kind and helpful! Still be careful not to brake it!It is a great size. Unfortunately I only got to use it for one day. The 24 hours it was in use were good. Temp. was stable and accurate.The suction cup kept un-suctioning causing the heater to fall into the sand. so this morning cleaned that area of the tank very well and tried to make sure the suction got a really good grip. Since the heater was plugged in I merely detached it from the suction gripper thing and left it in the water whilst I worked with the suction cup. I thought a good suction was achieved, slid it into place and went to put the heater part in its place. This is where my soul was crushed. Popped the little heater back in, and it taped the back of my aquarium glass causing the glass on the heater to break.I immediately unplugged and went to remove the heater. The tip came all apart. This released the black glittery sand that is all inside. UHHGGGHHH this is such a pain to clean up. It doesn't seem to be bothering the fish (hopefully it really is just sand) but it is everywhere! Cleaned it up the best I could, but its impossible to get it all. I feel as if i was glitter bombed. Now I'm out a heater, out the like $18 (don't feel right asking for a refund since it was my fault ) and spent a morning doing extra water changes. grr.However if you are VERY careful i think you can still enjoy this heater.
