Hatchback boot gas struts

Hi all, I've used the search function to look at results in the forum, but couldn't pin down any specific information about the gas struts on my car. It's a 2015 hatchback with manual opening. I thought the originals were a bit toilet and bought some new OEM ones from Autodoc. These fit OK and do work, to a degree, but there's no damping at the extent of movement. This means there's an audible and physical 'clunk' when the boot lid reaches the end of travel. It's awful. Has anyone replaced their struts with anything other than the hyper expensive Skoda ones to good effect, please?
