Its a .5kg stainless model....very light!
I have used it in strong current and so far it seems, as long as you let out plenty of line ( i use low dia. para cord )...it will work fine.
Also, you must, as usual, use a length of chain....
I will update this post as i use it more often.
Edit) so i have used it a good few times now and yes i would recommend it.. its so light its a doddle to use... the only negative point i have is, because you have to let out lots of line, anchoring accuracy close to structures is tricky...but still i wont change back for now!!
