The layout is very simple to use - I like how each tab shows what sections are available for that particular feature (walls/flooring etc). It's sometimes difficult navigating between tabs when having multiple documents open as some features link automatically through different pages if not already highlighted within this document but there was nothing i disliked about using speclink so far! If anyone has been thinking of purchasing speclinks then do go ahead- they're great value compared to similar products out there & worth considering especially where more complex layouts may be required. We have used the product extensively over 2 years ago during our build which involved 3 separate phases, however we still continue to utilize them regularly today.
