How do you like TestTLS?

Seriously? All five?!

I’m flattered, thanks a lot! Your hair looks beautiful!

While we're both riding this wave of joy, would you to give @testtls_com a shoutout on Twitter?

Not too bad, but not perfect.

Thanks a lot, I’m glad that you liked this website!

If you like, follow @testtls_com on Twitter to hear about new features as they are added.

Honest feedback, much appreciated!

So you think that this site could be better, understood.

Would you tell us what’s missing? Reach out either via @testtls_com or e-mail.

Almost 2.5 stars. Oh, boy!

So you think this website is shit, I get it.

Note to self: do not encourage users who rated below 3 stars to comment at @testtls_com.

Ouch, that hurts.

Father? Is that you? What can I do so that you will finally be proud of me?

Let me guess... you would have chosen zero stars if it were available, right? Let it all out via e-mail.
