I have three or four bit holders similar to this one:-
I find the 'pull it towards the drill' type *much* easier to use as it can be done by the hand that's holding the drill. OK others may disagree but this is what works for me.
I want to buy a couple more that work the same way as the one I like but how do I find out whether they do? I have not a clue where I bought the ones I have now and anyway I certainly didn't record which was which! :-)
So any pointers to ones which work the way I want would be very welcome. (I'm pretty sure that Wera ones work the wrong way for me).
