Advice for product testing

[Oreroy]

Hello
I'm doing some product testing campaign, my daily budget per adset is 10$.
I usually run each adset for 3 days.
However for 1 adset and after receiving 500 impression (in 1 day) my CTR is 0.5% and the CPC is 2.5$
Do you think there is a need to keep on testing this product or it's obvious that's a bad product?
Target country : USA
Product retail price : 30$
Cost :10$
Audience: LLA 1%USA (95% video views)

LLA recommended only from the purchase event.
