Yes i have one and i use it daily sometimes twice a day the only other appliance that gets used more is the washing machine. I never really had one before kids (1 house did) but now i couldn't live without it. I was just in the process of stacking it when the kids did something and i came to vent to friends lol.
I never rinse unless its like the rice cooker which i sit in a sink of water before putting it in otherwise it doesn't work.
I just use the Aldi or woolies cheap tablets and they are awesome hardly ever have to rewash anything and never more then i did with finish anyway.
