Anyone used Test4kits to test THC and CBD content?

Hey guys has anyone used the thc and cbd test kits to measure there buds for cbd percentage? Here’s their website https://test4kits.com.au/en/. Keen to get feedback if they are accurate.
Cheers

I've used my test kit once and it was awhile ago. No idea if they are accurate as i wasnt going to get a lab test to see. Evidently u can buy all the stuff online for cheaper.
