has anyone used Isc2Certs practice tests to study?

I'm currently studying for the ISC2 CC certification and I'm looking for some good practice tests to measure my progress. While searching, I noticed that Isc2Certs appears quite often in the results.

Has anyone used Isc2Certs for the ISC2 CC exam? If so, how was your experience?

So far, I've only been using the official ISC2 training videos and taking notes, but I'd like to practice with exam-style questions to see how well I'm prepared before taking the actual exam.
