I keep buying this product again and again because it works that well.
I have 8 of these currently running. I’ve had some for many years. I love that they do last and many are at the 3 year mark. Instead of just failing they give you a code letting you know it’s time to replace. I appreciate that. I find many of the low star reviews are user error . Do not run these while dry, do not drop them and continue to use them. Do not rinse them in extreme temperatures. Allow heater to cool off before removing it from tanks.I keep all of mine set to between 72 and 80. I have digital thermometers in each tank. These are extremely accurate. The tanks are in a space where temperature fluctuates and these have kept up perfectly.They are very easy to program and let it do its thing. If power goes out, I have not needed to reprogram. The size is perfect for my tank sizes 3- 5gallons . I’ve also used them in temp bins in the 2 gallon size.Safety concerns of mine are bettas going up to heaters and burning themselves. Not an issue here. No space for them to hide behind it, suction cups are strong, case around heating element fully prevents them from injuring themselves. There’s also no way for the fish to bump and change the temperature.Hope this helps

Nice Heater
CLIFF NOTE VERSION: Both heater work very well. The Nicrew is smaller, less obtrusive, but not adjustable. The Hygger is a tad larger, is adjustable, and has a large red LED readout of the tank temperature.LONG VERSION: I have purchased mini-heaters in the past and they either didn’t heat or fried the water. I long ago learned to do the bucket test. I purchased the Nicrew Mini (15 watt) and the Hygger (15 watt). The Nicrew is smaller with a preset stated as 76 degrees F. The Hygger is adjustable with a large LED readout. It is super easy to set. There’s a rheostat type adjuster that’s on the cord. The readout is on the heater. That makes it easy to bump the heat up or down without sticking your hand in the water. The downside is that the light on the heater is noticeable in the tank. You’ll want to hide it with plants or décor if you’re going for a natural look.Both were placed in a 3 gallon bucket of 70 degree water for one hour before plugging in. This is a manufacturer suggestion, and, IMHO, failing to do this is bad for the heater. The room was 70 degrees. I plugged them in and set the Hygger. An hour later both buckets of water were at 74-75. That temp held for 24 hours, even though the room temp dropped to 65 at night. I’m now using the Nicrew 15 watt in a 2.5 gallon tank and I’ve very happy with it. The Nicrew holds rock steady at 74. I’m keeping both heaters. I’ll use the Hygger in the winter when the room temp is much colder and I may need to use the adjustable feature to compensate for the room/tank temps. I used a scientific thermometer for my readings. Big thumbs up for both heaters. I suggest you do the bucket test as heaters can vary.

Very good heater.

easy to read
Working well and easy to read… kind of bulky compared to the old glass tube style heaters but the style change is growing on me.

Lasted 14 months, then End of Life failure code ***PER DESIGN***
The availability of small 25-watt heaters for 5-gallon aquariums is extremely limited. This one seemed like a decent quality heater for a fair price. After 14 months of use, I noticed the display was flashing between ‘EL’ and the water temperature. The heater was still functional, the red heater light properly cycled on and off as the heater cycled, but I did not wish to risk electrocuting or cooking my betta because I ignored an obvious warning light. It seems that these days, for the price we pay for things and the service that we receive from them, it is more like we are renting these items than buying them. There is a planned, designed, and limited service life, and the item is priced by its approximate value per month. Ce la vie.I still expected more than 14 months of life from this heater when I bought it though.***UPDATE***As stated previously, quality 25W aquarium heaters are hard to find. I reordered this one because it seemed the best choice of available options. Upon opening the new one and reading the instructions (GASP!), I read about the EL end-of-life code. It is set for 10,000 hours. Got on the internet and asked how many hours in 14 months, and guess what? Almost exactly 10,000 hours! So, my only real beef is that this is not made clear in the product description. If I know that I will only get 14 months of service out of this device, then I can decide if it is worth the price. IMHO, it is. And after thinking about it, I appreciate that the device tells me to replace it BEFORE it cooks all my fish, which is what my last aquarium heater did, without any warning. Sure, I got several years of service out of that one, but at what cost? At least this one lets me know when it is a good idea to replace it. Upon further consideration, I am changing my review from 2 stars to 4. I would have given 5 stars if it had been made clear up front that the service life of this heater is 14 months. As long as the price remains fair, around $18 or $19 (or less!), I think it is worth that price and would have earned 5 stars if the product description made it clear that it would only last for 14 months.

Product seems good but instructions poor!
I now have 2 of these heaters for a 2.5 and a 3.0 gal aquarium, respectively. After 8 days of service I am happy with their performance.The problem was the initial temperature set up. The instructions were poorly translated from the original Chinese. After getting an error message on the thermostat that the heating element was dead, and then not being able to contact the manufacturer, I decided to try a different plan. My approach worked!When the 2nd heater arrived I used my method and had immediate success.

I had a different brand heater and it was always a few degrees hotter than what I set it to (around 75)I put this heater in a tank that’s a couple gallons bigger than what it’s rated for but since the temperature is only set to around 75 it is perfectly stable and has no problems. It’s nice and small

I finally have an aquarium heater that heats up the tank and keeps the heat in it. Digital is the only way to go.

Nice smaller size for nano tank, just wish cable was more flexible. I’ve had more powerful thermos with cables easier to tuck behind plants.That being said, not unhappy with purchase. Easy to adjust temp and lights a bit bright, but it’s nice to see running temp.
