Cebu Pacific 10kg Carry-On: How Many Bags Are Allowed?

For those who have recently flown with Cebu Pacific with the 10kg carry-on baggage allowance, can you share your first-hand experience?

How many bags did you actually bring on board? For example, did you have one cabin luggage plus a backpack/personal bag, as long as the total weight was within 10kg?

Were both bags weighed or checked at the airport?

Thanks.
