The eniTAB360 comes in two sizes: small and large. The small is designed for 8.5” screens and smaller and the large is for 8.5” or more. We were sent the small model to review. The design is well thought out and very sturdy. We like how the edge that comes in contact with the flat surface is rubberized to prevent scratching. The green circle part that sticks to your tablet uses silicone based polymer micro-suction technology. The suction is very strong and you need to use the included smooth card device to have it loosen the grip off of your tablet. If you lose the remover, a credit card could work instead though it could cause some potential scratching.
