Hey @phantomchameleon - Sorry to hear about the lack of oomph. @Dignon is correct regarding the difficulty QCing items we don’t make in house, but each panel is tested prior to install. However, we have swapped a small number of struts with issues in the past, and some customers choose to upgrade to stronger options. The latter option is typically for those who are installing accessories like Maxtrax as seen here.
Colder temps can reduce a strut’s performance when opening, but I’ve had my own GFC for almost 2 years now without issues or noticeable lag unless the temps are pretty frigid. Best way to sort this out is to reach out to our support team or submit a SRF by clicking here.
