You can see exactly what is inside and I've had no problems with the lid

overall,very happy with it ,looks stylish in the kitchen Filter in spout slows the flow considerably but apart from that frustration it's fine

It had never become an potential electrical danger even for electrical protection devices etc to be triggered

Second one the spring/latch/button to release the lid was in steady decline making it hard to open, also the filter kept falling off but this was before the glass shattered while pouring boiling water

I ordered this without reading the reviews but then thought about cancelling it

To open the lid you had to press the button and insert your fingernail under the back of the lid to open it!!Also the clear outside gets extremely hot and I burned myself many times!If someone would like to contact me I will send it back (it is sitting here in a box) as I had already deleted my emails with order numbers on etc
