Unsure of which BoobiTrap fits your needs and your phone? Generally, next-generation phones like the Samsung Galaxy series, the iPhone 5 and 6, and the Motorola Moto X and Turbo fit BoobiTrap much better. Additionally, if you like to keep a case on your phone, BoobiTrap is the choice for you! Unfortunately the iPhone 6 Plus and the Samsung Note series are too big for either BoobiTrap.
Smaller phones, such as basic pay-as-you-go, flip-phones, or iPhone 4's fit well in the original BoobiTrap Compact.
