Lube that is, this case is slippery. For months I used the UAG Metropolis with zero issue other than wanting a change from a flip case. So I opted for this bad boy. Bad being the operative word. The first thing you notice is the overwhelming bulk, second how smooth it is. Polished even like Spigen dips every case in car wax before they send it out. But I decided to give it a try anyway, within 30 mins of being at work I jumped down a stair and watched my phone fly out of my pocket like the hulk at a jelly wrestling tournament, and just like that an action I had repeated 50× a day with the metropolis attatched suddenly turned my phone into a rocket even Kim Jong Un would be proud of and much like the damage Mr Un's rockets would cause I was left with a large unwholesome scratch down my devices screen. My final verdict, no thanks ya slippery bugger!
