Is intuitive to use and provides valuable insight into people you may be dealing with
Its really a cool site. All the predictions were true. It really helps to understand your business partner.
Incroyable de véracité et de pertinence ! J'en reste baba... et je suis fan !
Insanely accurate! This tool is very accurate and can be helpful in building new network and in sales, or simple to help you to get to know another person better. I wish I could use it with other platforms, like FB and IG or in email assessment.
WOUH!!! Cryrstalknow is amazing extension . My personality reads are acurate. I have work on some aspects though. I love it.
I just got it but it dissected me from my LinkedIn profile eerily well.
Crazy Accurate
This is amazing!!! WOW
Simply amazing! I'm beyond impressed
This should be ILLEGAL (jk lol). This is so accurate and totally value adding.
