Menstrual cups

Jessica☺️😘♏️
Does anyone have experience using menstrual cups? Any advise? Is it comfortable? I absolutly hate tampons,  their uncomfortable and make me sore, are menstrual cups the same as tampons as far as comfort when putting it in? How long can you wear it? Etc..... Anything you think I should know about them, let me know. 
Ps. How much do they generally cost?
