Brilliant little heater.
The media could not be loaded. I purchased this for a shallow water section in my terrarium and am completely blown away by it's value for money! It's feels very well made and comes with a very handy built in thermostat which is button controlled. Tap the button and it will go from 18 to 34 in .5 jumps. I have had mine set to 27.5 and it has produced a decent amount of condensation, which is what I was after in the first place.It also has a built in thermometer, and the light goes green when the temperature is met, but also shows on the lid screen.Just a brilliant and great value little heater all round!

Great for the size
Absolutely perfect and a great size to hide in a fishtank so it's not obtrusive and invasive would recommend 👌

Filter and heater

Only worked for a few months 👎🏼
Great and easy to use but didn’t last long, thermostat must have gone because I came to find my tropical tank really cold and fish looking unwell yet the temperature reading on heater thermostat was higher so it wasn’t coming on to heat.

Good compact heater.
Easy to use and very compact. Superb customer service. Good useful temperature display.Purchased for our shrimp tank, where it was easy to set up. A bit too easy in fact, kids love to press the button and the temperture increases by half a degree - fortunately this is clearly displayed and rectified. Unfortunately the heater only lasted 4 months before it stopped heating - the temperature display clearly showed the temperature drops and a spare heater was brought in. Minlo have responded quickly and provided a replacement under warranty they also offered full refund. Fingers crossed it will last because it is liked.I haven't used the suction cup, and the rubber protector on bottom of heater did warp over time, I will remove it from now on.

Neat and compact.
Keeps my 60 litre tank at 25 degrees, the temp display is a bonus as well.

Ace seller
I bought this heater last September and been working perfectly for my needs. The heater itself is well made but Sadly for some reason it stop working this week. I reported it to the seller who responded in less than 12 hour period and offered me with a replacement or a refund without quibble. This is the after sales service that are so rare nowadays. So yes for that reason I will definitely buy again from this seller. You are an ace! Many thanks
