All of you have been very helpful! I never used the bit it's still sitting in the gap between my bed and dresser haha. For all of you asking, I orginially bought the bit because the woman at tractor supply suggested it to me. She claims she has been riding since she was very young I came straight out and told her that I was a new horse owner and needed a bit. I also told her I didn't want one that was very harsh because I obviously hadn't mastered riding and didnt want to cause discomfort to my girl. She gave me that bit and then I made the post on here; after that I talked to one of my friends about it she told me not to use bc it was a harsh bit that isnt really used alot.
Your friend was right. When you are an experienced rider with soft hands who has a horse that needs one and uses it as a training tool then you can use one. Until then it's best to stick with a regular snaffle like this or this:
Depending on what your horse likes. If you have to ask where to put the curb chain (which you don't use on a snaffle) you are obviously not ready to move off of a snaffle. Good for you for double checking, always get second opinions.
If you aren't having problems handling the horse why use a twisted snaffle? I would get a plain snaffle and you can use a cord curb if you want to keep it from pulling, but you do not need a curb with a snaffle. Curbs are for pressure with a snaffle there is no pressure.
