We tend to use a lot of oil while cooking so I was looking for a option which would help me to control the amount of oil we spray into salads/ air frying items .This oil sprayer set. really helped us to keep check on the oil we tend to use on a daily basis. You can actually control every ounce of oil going into your bowl. There are 2 glass bottles in this set along with a small funnel (for pouring oil into bottles) along with a brush to clean the spray pores. Looks elegant and since its transparent with all measurement markings , its easy to keep a tab on the oil used. I feel its a good purchase for the health of my family.
