I have 2 of these on my Ranger on Veeshan. Here are my opinions on them:
1: For soloing, they are pretty mediocre as far as damage outlay goes.
2: Great in fights against caster mobs (More hits = more chances to interupt casting).
3: Decent in groups because you can do a fair amount of damage while only rarely getting agro.
Just MY opinion on them.
