JUWEL Aquarium - Digital Thermometer 3.0 - Suitable for all aquariums

Quite accurate compared to cheaper thermometers, as far as i can ascertain there is only half a degree Celsius difference between the set heater temperature and this thermometer, the cheaper thermometers i was using were 2 degrees Celsius out in comparison, i bought 2.they are considerably more expensive than the cheaper ones but you do get what you pay for, accuracy and reliability, easy to position on the tank and easy to read large display.

Easy to install and read. Attaches to the aquarium lid easily and the screen is clear.

As usual Juwel products are more expensive — but you get value for money as the product is excellent quality and it shows!

It’s great to keep an accurate temp of the tank, only down side is it don’t stay stuck on, every few days it falls off

Expensive, but looked well made. Accurate and excellent readout. But after three months readout started to fade in places. Now just a few lines and dots. Don’t waste your money

This was bought for a b,day present so bought 3 weeks before-on opening this today the battery was very corroded? and cannot be used with item.

poor build quality, falls apart, had to fix with super glue out of the box. Looks nice , but doesn't fit properly as advertised in jewel tank
