Unusually at this price point is the existing automatic function: When needed, the screen works at your fingertips just one. A function that know especially appreciate urbanites and public transport users a lot when you want to quickly get on the bus / rail or quickly want through a door.
Anyone looking for a low-cost automatic umbrella, can safely access here. From the first impression, it is likely to exceed the lifetime of several discounters umbrellas and quickly pays for itself thus.
PS: Of course, the screen is 100% leak-proof ;-)
