100W Aquarium Tank Heater (20~34'C / AC 220~240V)

Pros: Very good product. Easy to use, supports the exact temperature you chosen on it. 100 Watts is enough for 50 liters aquarium and temperature difference between the room and your tank up to ten degrees. The rubber stickers are very good - stick to the glass tightly. The red light shows you when it works.

Cons: nothing so far.

Other: Could be a beat cheaper but considering free shipment the price is good.

Pros: Good quality, well built and just like every heater that I bought from big brands but payed twice or more... I have a Oscar in my aquarium and sometimes it tries to break things biting and hitting it, but until now its resisting well... Also the air humidity level is very low these days in my city, and the water is evaporating a lot from the aquarium, so i left the water under the minimum level required for the heater and nothing heapenned. Already had to change the heater of another brand because of that...

Cons: Can't think of any...

Other: Functional and strong. Buy with confidence!

Pros: good plug and play tank heater and the length is usable in almost any tank

Cons: ordered mine with a 220 volt round pin plug and received one with a flat pin plug however I just replaced the plug

Other: Only time will tell if this heater holds up but at this point I am very happy and will buy more in the future. I recommend this heater to anyone in need of one and PS. I have seen the same model and brand at the local shops for 3 times the price
