Mapo Citrus Fruit

Today I tried mapo citrus fruit. I bought it online with my grocery shopping. This was new in their stock and I bought two of the fruit to try it out.
It is something between grapefruit and tangerine.
Me and my kid both didn't like the fruit. I think it is flavourless and it smelled like some car oil when it wasn't peeled off.
Definitely, will not buy that  fruit again.
