Review on Revolutionary Zero Waste Cap - Say Goodbye to Plastic Waste! by Renee Hackbarth

This product works as intended. It comes with 2 different sized inserts but you can only use one at a time so I find it quite expensive for what you get. The lid is nice and wide, which prevents your lotion bottles from falling. Since many bottles have the same opening size, I've found that you can simply use the shampoo bottle's flip cap on the lotion bottle once the contents are low enough for the pump to stop running (and the top of the shampoo bottle is free). . !). See the photo I've attached. The Zero Waste cap is on the right side of the bottle, while the other two bottles have caps from other products.
