1.0 out of 5 stars Fish Killer 6 May 2012
Size Name:150 Watt|Verified Purchase
Installed heater in tank as stated on box , light came on to show was heating, did not have much to do because I had just removed a lower watt heater from the tank. This heater was to be a upgrade. Heater switched off at correct tepmerature of around 25deg. Went to bed, woke in the morning to find 5 dead fish on the tank floor, temperature of tank was down to about 18deg. Heater had not switched back on when temperature had gone down and yes I had set the correct temperature on the heater by using the built in guage. Gave the heater a tap with finger and low and be hold on came the heater light again and heat. Very very dissapointed with this Interpet product. Will not use again thats for sure.
If you do get one, just keep your eye on it for a while to make sure it is working correctly , Don't loose your fish!

5.0 out of 5 stars Does its job perfectly 5 Aug 2012
Size Name:100 Watt|Verified Purchase
It arrived quickly and is perfect for the size of my tank. Its been running for a month now without a glitch and it was very easy to set to the desired temperature. The little red light letting me know its working is a nice touch to, though I use a separate thermometer inside the tank to actually judge how well its doing its job. So far so good!

I'm very pleased with both the product and the price.

5.0 out of 5 stars Fantastic value 14 Mar 2013
By oscar wilde TOP 1000 REVIEWER
Size Name:100 Watt|Verified Purchase
I have two of these running in two different tanks and so far they are fantastic. They keep a 23l tank and a 46l tank at the correct temperature all the time. I would highly recommend this item. I would say that it is very important to have the heater at an angle in the tank as help the built in thermostat keep the water at an even temperature.

5.0 out of 5 stars Interpet 100w heater 10 Aug 2012
By Graham
Size Name:100 Watt|Verified Purchase
Got this for a new 60l tank I was setting up. Not sure if the thermometer setting is accurate, as I've set mine to 26C to get a tank temperature of 24C but with a cold room anyway I hadn't expected anything else.

The heater seems well made, looks good, and is working well - I would have no hesitation in recommending this heater, (although I fancy the new E series from Fluval for my main tank)

5.0 out of 5 stars Brilliant aquarium heater. 14 Dec 2011
By B. Mand
Size Name:50 Watt|Verified Purchase
I purchased this product for my 19 litre tropical aquarium (it was recommended as the tank is also a product of Interpet.)

So far, it has been brilliant. You can see when it's adjusting the water's temperature because of the red light switching on during heating, which is reassuring. I have a rather cold bedroom (where my fish tank is) and the heater seems to be on quite a lot, however, the fish (3 guppies and 2 danios) are comfortable and happy, and have been for a very long time so it must be doing it's job.

I can tell the water is warm from touching the glass and putting my finger in the water. I do not, however, have another thermometer to check the temperature so I cannot tell the accuracy of the heater, but as I mentioned, it's always seems right.

Setting the temperature is easy too, it's simply twisting the cap this way, or that way, depending on the temperature you want.

It's very durable and has stayed stuck to the glass, never had a problem and forget it's there. It's rather big, but I have a small fish tank so it probably just seems that way to me.

The power adapter is not too long, but it's not too short either, this can be easily fixed by an extension cord, of course, and the power adapter's WIRE can be submersed if need be safely.

Overall, I would definitely recommend this heater to anyone, it's from a reliable company and does it's job very well. I can't say whether it will be good in experienced or bigger/complex tanks but for startup/simple tanks, this is an exceptional product.

4.0 out of 5 stars poor temp control 11 Jan 2012
Size Name:300 Watt
bought this as a replacement for my existing 300w heater was the correct output as recomended for the size of tank then the problem
the heater will only give you a constant temp of a max 28 celc which it doesnt state until you read the box, no help to me with discus ,so go for a higher wattage if running higher temps. Apart with making sure you dont need higher temp this is a good product and will do the job.

4.0 out of 5 stars Good value 26 Nov 2012
Size Name:200 Watt|Verified Purchase
This works well but I would have liked the plus and minus signs to have been more clearly marked so that one could tell whether you were turning the heat up or down.
