This is very good to bring with you on the round, but be careful - I hung it on the towel loop, and when I grabbed out for the towel, that nasty steel brush was suddenly between (or rather in) my fingers. So, be smarter than me and hang it somewhere visible ;)
But it is a good tool at a fair price, and you will soon find it to be servicing you many times during a round, either using the soft brush or the steel brush for cleaning your clubs.
