any1 here got experience with the slamman?

i train 5 times a week 3 or 4 in the gym and 1 at home.
but now the boxing section of the gym is closing for 1 and a half month.

i got a speed Ball, heavy bag,skipping rope,weights and plenty of room for shadowboxing and all at home.
but now i see this slamman thing.
trains your reflexes too which i cant really train at home.
but is it any good? is it fast enough to train your reflexes?
does it give you enough resistand when you punch it etc etc

i mean is it worth my 299 euro's?
