Had a look at Quatt's website. Just a quick remark:
Requiring to fill in information for a brochure about your product, feels weird & I'm not willing too, but ok. However, automatically agreeing to receiving 'marketing communication' & agreeing with your cookie policy when pressing download is definitely not ok. Not from my personal standpoint, but more importantly also not by law (GDPR) although IANAL. Might be a good idea to tell your marketing colleagues about this. Please remind them not to be behave like assholes. Nobody likes forced "marketing communication"...it's just a euphemism for spam. Take care.
