Expensive, and poor packaging design.
These vials are very expensive. The saline solution is ok. The packaging is TERRIBLE.  When the vial is opened, the hole in the vial doesn’t squirt directly down into the lens consistently, causing a lot of wasted product.  The vials do not stand vertically, so they leak or become contaminated.  I only bought this brand because Scleralfil was backordered.
