The heater is great so far and has been working well keeping the temperature stable. Overtime the sticker inside has slightly burned but not a lot to be concerned about. The clips that hold it in place have not lasted though, and they come loose from the suckers all the time. Other than that it’s pretty good for the price.

Extremely happy with the 150w heater for a 155L tank. Heated very quickly and achieved the desired temperature within about 4 hours and maintained an even temperature from about 6 hours onwards. I was able to transfer my fish to their bigger tank, earlier than I anticipated. Very effective, great price, highly recommend! 🥰

One of the best value for money 200w heaters available. Seems to keep good temperature for my 4 foot tank
I love this heater I have had it for a couple of weeks and its great. Just warning you that the light will go off which means the heater goes off when it hits the temp you set it to this is the thermostat it is to save energy. So the heater is not broken its just saving energy I tested this because the light turned off and as soon as I put it in the cold water it turned on straight away.
I got two of these from the website and got them delivered to the wadebridge store..am very happy with them. The only thing i found was the power lead was on the short side but no problem with a extension lead. Might just of been my tank a little on the lage side being 6 foot. Two of them had no problem heating 650 liters. Am very happy with them. Would recommend 😁
Seems to be doing a decent job at regulating the temp in my 200L tank. Packaged well, delivered quickly and overall I am happy with my purchase. The telling thing with heater/thermostats is for how long they keep doing everything properly. Time will tell
Had 2 for 6 months - no issues really with the heater itself - seems to work fine. The problem is that the numbers that indicate where you are setting the temp have worn off the sticker. While you should never expect a non costly heater to heat to the number you set it it's annoying that I can't see the numbers to adjust after 6 months of use. They've rubbed off. Doesn't make it unuseable just a pain. Even just a plus or minus molded in would be great.
