Smooth from start to finish
Validation was a single email click. No documents, no phone call, no waiting on anyone. The CSR instructions were clear enough that I did not need to look elsewhere.

Straightforward purchase
Third certificate I have bought here and the process has been identical every time. Works on every browser I have tested, desktop and mobile. Better price than the certificate authority charges directly, for the identical product.

Needed HTTPS on a small site without any paperwork, and this was exactly that. The site seal and the padlock both showed up straight away. Happy to have found a supplier that answers questions properly.

Did what I needed
Set this up on a staging box first to be sure, then production. No surprises either way. Chain installed cleanly on nginx with no intermediate certificate hunting. The only thing I would change is nothing. It did what it said.
