I'm looking for a full-body protector for my N900 (I've tried a variety of cases and none of them have really suited my needs and made the device too bulky) and not sure which to choose between InvisibleShield, Clear Protector extended and Clear Coat.

Does anyone have any experiences of using these three? I'm not so interested in how their actual screen protection works since I already have a Vikuiti protector I'm happy with, but I am interested to know how much protection they give the back and sides of the N900 and which of them are easiest to apply. I'm particularly interested in which ones offer the most protection of the sides, since it's not very clear from the pictures/descriptions of them which actually protect the sides. Any info from users of these very welcome.
