Thay are actually pretty decent. But it’s hard to get replacement springs and it seems to be a bit of pot luck whether you get a suitable one. (they do have a little preload adjustment but that’s no use if the spring’s not right)
My main finding was, really stay on top of the maintenance- regular lowers services absolutely essential, because the sealing isn’t great and the internals have absolutely no tolerance for dirt- lots of soft plastic. Keep them in good shape and get a suitable spring and they’re one of the better budget forks but, those are big buts.
