The best thing about ghostfern are that it's so easy to use! You just need an internet connection, no heavy machinery or experience needed for installation/construction - plus you can easily create different shapes than only square ones by using some templates provided in their website (I have made simple arches with them). I do not personally dislike anything yet because they seem pretty good overall :P However there might be something i don't know which could turn me off from purchasing one later downthe line if this comes up ;D For now everything seems great =) Just take your time deciding whether these will suit what exactly u want done at home since installing requires skills like any other project where precision matters :) It helps having someone else help install as well even though my DIY skill level isn;t very high either ;) There really hasn’ t been much problems after putting mine inside our living room apart form minor dust.
