Just place the device on top of any overtightened bottle or jar, press the button and voila, the lid will be opened in seconds.  That's literally all you have to do.  It's so easy that there is no need to even hold onto it while it works.  It's all automatic. Perfect for seniors, people with arthritis or anyone who has struggled with an overtightened lid.  In other words: everyone. 

An adjustable design allows it to be used on all jars of any size.

No more having to call someone to come and open a jar for you.
