yes, I first had a japa mala, a wooden one, and would chant the maha mantra on this... long time ago... I currently have a traditional catholic rosary made of wooden beads, and maybe I will get em out and do a round every year... I also have a beautiful rose quartz mala which was given to me by a beautiful old lady who I met in a buddhist community who thought I needed a lift... again, I don't use the mala often, maybe once a year...
I did spend a lot of time chanting mantras on the rose quartz mala after I have received it, but it would snap a lot, due to its construction, and in the end I started tying it together with fishing wire...
I would chant as a means to alleiviate anxiety, (at the time I was quite anxious, and it helped, when in public places, on the bus, etc, I could just keep it in my pockets and finger the beads and silently chant my mantras), I would also chant to prepare myself for my "not-thinking" meditation...
great if u need to fill the void, and great if u need a crutch, but not so great if u put too much religion in, to the exclusion of mundane convos and watching the world go by... otherwise, ur just constantly reaffirming ur religious beliefs, over and over again, and self conditioning...
