Can I use howsecureismypassword net? Is it safe?

It's a small thing, and the safety of the solution is not compromised, but bear in mind that http://howsecureismypassword net/ contains 5 different cookie sharing websites (as reported by Collusion), so the tracker networks have recorded that fact that you have been there. Less security minded users may then fall for promoted security products on other websites that share these tracker networks. i.e. why you'll now find various password vault programs being advertised to you on websites for a few days!
