I've not had the oppertunity to try KJ DIY products but I've been meaning to. All my DIY juice is put into glass 30ml bottles. I never use plastic. Seems like the odors of the juices gets out and or into other juice. Someone up above said something about it not being safe in a house with kids and pets... but I've always kept all my juice bottles away from pets, kids anyway. Plastic or glass. Since I've not purchased any KJ DYI yet, nothing will have changed for me.
