Key Features
✔ Smart Safety Alerts & Auto Shut-Off
Built-in dry-run protection and an overheat guard automatically switch the heater off if water runs low or the unit overheats. Audible alarms and LED error codes (“Er”, “EE”, “EU”) provide instant warnings to protect your aquarium and prevent damage.
✔ Precision Temperature Control (15–34°C / 59–93°F)
An external digital controller makes adjustments simple—no need to put your hands in the water. Real-time LED display and indicator lights clearly show the heating status.
✔ Compact, Low-Profile Design
At just 10 cm long (4”), this heater fits neatly into nano tanks and tight spaces while still delivering consistent performance.
✔ Auto-Memory Function
In the event of a power outage, the heater remembers your last temperature setting—ensuring uninterrupted care for sensitive aquatic species.
✔ Fully Submersible & Easy to Install
Mount vertically or horizontally using the included suction cups. For best results, place at least 12 cm (5”) below the water surface in an area with good circulation.

Gets the job done, not sure for how long
Color: Rustic Wood
These were hard to assemble due to the screw needing to go behind a metal bar, meaning all of my shelves are wobbly and one is starting the cave in the corner some. Overall not too bad for the price (got it on sale, wouldn’t recommend paying full price. Also didn’t realize the wood was unfinished so it’s splintery (be careful, I got several splinters when assembling and putting up).

A great $30
Color: Grey, Color: Grey
The wood is cheap particle board (probably better bc they are very light weight) but the brackets are plenty strong and sturdy.
Advice on the install: your walls may not be exactly 90 degrees. Install one bracket after the other is holding the shelf up.
Super pretty.

Great shelves but be warned.
Color: Grey
These shelves are great for small items and can definitely hold up to their advertised weight if mounted in a stud. However, DO NOT use the longest screws at all. All the screws are low quality and are likely to break. The medium length ones are sufficient for everything. If your wall faces an exterior concrete wall: break off the tips on the dry wall anchors, they are too long.

These are a great corner option
Color: Rustic Wood
Was looking for something to set in some corners, and these fit the bill greatly. They are nice looking and easy to assemble and then put up. They hold a plant and some rock items nicely. A good purchase.
