This is my second Elementis Jug. It lets you know when the filter needs changing, but although it fits into the fridge well during the summer, the electronic display stopped working after being in the fridge. So, if you want to put this jug in the fridge you would be advised to remove the electronic display first. This would be easy to do but a nuisance if you are regularly putting the jug in a fridge. 
The non slip handle is nicely balanced and makes the jug easy to fill and use.
The jug also has a non slip base.
I have the smaller version as I would struggle to lift the larger one when full.
Overall I love my jug and would strongly recommend it.
