I liked mine, I grew a couple my last grow and it grew out fine, and I stressed the shit out of mine. For whatever reason because they are feminized you will get everyone saying they'll herm on you, its not always the case. Barneys is a halfway decent fem seed breeder, if I had to buy feminized seed I'd more than likely choose a barneys strain, they have a selection to choose from thats for sure.
If you get a herm out of the ones you bought its probably due to something you did rather than the genetics, not saying your a bad grower or anything like that, but its the truth, most things that go wrong with the genetics of todays better known breeders seeds is user error.
Just make sure you keep an eye on your gilrs all through flower keeping an eye out for the dreaded nanners and you'll be all set, if you see some, chop em off or chop the plant all together, may be worth it if you only find one and dont want to chance an accident.
