Expensive service. The plugins do not promise what is described. Every time I make a custom setting, I have to contact the technical support afterwards. Debugging the service takes a very long time. I have been optimising my images for weeks and the news keeps coming back that there is still room for improvement. I had to spend 5 hours with the support to finally get the back up working. Three weeks ago I opened a ticket because the asset optimisation does not work. The ticket was closed and the part still doesn't work! I always have to deactivate all plugins to make it work.
