Chess clocks are really useful. You can quickly make moves that don't require much thought, which saves you time for more complex moves.
However, 4000+500 is too much; it should be less. Although, when I used to play with less time, I sometimes couldn't keep up. But it's okay; after a few games, you can get used to it and move faster.
P.S. This is precisely why I play Heroes for 1-2 months and then stop, as it consumes a lot of time.
