For now, I had the original Flipcover tuned, very chic, well made - but unwieldy, you always have to first fold the cover backwards and can only then get going.
With the Samsung EFC I just need to pin pull out and off you go.
The Case is perfect, the buttons are almost better with the case to operate as a non - good pressure point, excellent tactile feel when feeling the buttons in the dark, well protruding edge at the front, so I can phone sometimes to the "head" place , When muting functions, call rejection and the front turn perfectly.
Combined with a protective film, I can recommend the Case warmly. Since good work has been done - by me 5 stars (and I'm not from a telephone company, Samsung or anything else!). BUY it to you!
