The reason for buying these was for industrial cleaners due to how basic rubber seals deteriorate when exposed to harsh chemicals. These bottles seem work in that respect. However, the overall spray head design is weak and unreliable. The particular defective bottle provided in the attached picture is stored inside my house. I picked up a botte by the spray head and it cracked almost completely around the outer diameter of the bottle cap attachment. I caught it in time before the bottle fell, potentialy spilling my bleach water mixture on my clothes and carpet. No bueno!
