Question Should I Buy KernelCare from Plesk Extension or from KernelCare Website?

[Wellington Nunes]

Hello my friends, I have a question about using the KernelCare extension for Plesk (Linux Ubuntu 16.04).
Should I purchase the extension from the Plesk store ($ 5.00) or buy the version directly from KernelCare ($ 3.95) and install via SSH? Are there any differences?

Thank you for your help
