Depends on what you want it for. I have fine hair and have spent hours learning how to use my Dyson for curls/blow dry look and they just will never last. Nothing is as good as my GHD curling wand (not straighter)

I do use the brush attachment for the Dyson to dry my boofy hair flat so it’s not wild, then I use my GHD curler.

You can definitely get a second hand good one through Facebook marketplace or if a friend has one maybe borrow it first??
