Input:
We purchased this for our two boys (ages 7 and 11).  They like it a lot.  They use it for punching and kicking (they both take karate).  The only problem with it is that the base where you fill in the water has started to leak (after 2 days).  It apparently comes with a repair kit, which should have told us something about its durability I guess!  We have yet to see if the repair will hold or not...

Options:
A: very positive
B: positive
C: neutral
D: negative
