Uelfbaby Aquarium Heater 300W LED Display Titanium Tube Fish Tank Submersible Heater

I like the smart look with digital temperature display. An external control pad makes it convenient to set the temperature. Worked well to maintain temperature at 24 C with a tank of 400l.Only issue I have now is after 11months it can't hold the desired temperature setting. The red light is on but the tank is not being heated and stays at around 21C which is the room temp. My guess is, the thermostat works but the heating coil is shot.Thought I would at least get a year out of it, Oh well.UpdateI have since been sent a replacement heater, no quibbles!

A replacement heater was needed at very short notice, I decided to order this option, as I was currently running a well known brand external heater which failed 2 days before my holiday.This heater was easy to install and set up, you control the desired heat via the little in-line remote control, which is very accurate.I've located the remote conveniently under my aquarium inside the cupboard and for added piece of mind there is a red and blue led on the top of the submersible unit, nice and visible at a glance to determine whether the device is heating up or at optimum temperature with the actual water temp reading displayed.This heater has now been running perfect for about 4-5 months and is still as good at keeping the temperature regulated as it was when brand new.

UPDATE: stopped working after a few months. Just says its heating and never heats. Warranty process was a pain so I just bought a different one. I run a 150L tropical live tank. My original heater failed and I needed a new one quickly, looked around for ages reading reviews of the cheap ones which were all blowing up and frying the fish! I came accross this one, a little more money but looked different and had good reviews. I decided to take the plunge!Bought on prime as needed quickly, as ever arrived when it said it would the next day by a very polite driver. Unboxed the heater and as with everything I buy, I disassemble it and check it's build quality out, at the end of the day if its rubbish its going to kill hundreds of pounds worth of fish. Looked great so put it in the tank and it is important that it is fully submerged, nothing pertruding. It can be mounted horizontally or vertically not diagonally. I switched it on and.... E1 error code! I tried a good 4-5 times before calling amazon to get a replacement but as the guy was sorting it out it worked on the 6th attempt. Bare in mind guys that this has been in the back of a cold van in transit so leave it in the water for a good 15 minutes, this was my mistake. Tank was cold running at 21 degrees as no heater for a while, once this was on and I set the temperature (remember to set 2 degrees above what you want, this is stated on the instructions) it heated the tank up to 27C within 45 minutes, thats awesome.Looks good, can see the temperature when away from the tank and is very accurate.Feels like I've spent £30 on a £200 heater, very chuffed!

The heater is exactly as described and is working well,since I installed it a month ago. The temperature cycles by about 1 degree but do find it a little disconcerting that you have to set it 2 degrees above what you want,this is mentioned in the instructions. The temperature readout on the Heater is excellent and can be seen quite clearly,even from 3 meters away.

This heater is a fantastic buy, regulates the temperature perfectly, the first one I bought was faulty but the company replaced it with no hassle at all, well worth the money

Pretty easy to set up, holds temperature well, external setting of temperature is great: no more trying to tweak the heater by guesswork whilst it remains under water. Digital display is a nice touch. My only reservation is in the instructions it seems to imply that it may need replacing after a year. This may well be a translation issue and it could be it is referring to the warranty lasting a year.Update: unfortunately the heater just stopped working. I contacted the company and they immediately gave me a full refund

Compared with a thermometer temperature varies by 1 degree so not bad. only time will tell how reliable it is. I have it totally submerged, so I can readily check temperature I have placed it so it can be read through the plants, which also disguise the lead down the inside of the hankPurchased this in February 2019 lasted 8 months went onto error code E 2 instruction reads temperature went over94 degrees F will now not heat. The heater has been in the tank never out of water, installed as instructed.Leaflet warranty available for one year, does not give contact details. I will try to obtain refund or replacement through Amazon. Not reliable if only works eight months risk to fish if I had been away

I'm really taking a liking to these titanium heaters. I'm using this to heat up water in a tub before water changes, and it's good knowing I'm not banging around a glass heater when moving this about. The temperature setting seems to be working really well. I set it to 1 degree higher than what I want, this seems to be working well for me. Being a 300W heater, make sure it's been off for a while before handling it. I made the mistake of handling it before it cooled down. Not a good idea!Overall, very happy with this titanium heater.
