We use this product in a long term care setting, and assisted living setting. This is an amazing product that make nurses jobs much easier than crushing meds and using kitty litter or coffee grounds to destroy them. However, listen to the manufacturer's directions and do not overfill the bottle. The bottle could foam up and come into contact with your skin/face. Overall, very easy product to use, just dump pills in and tip the bottle twice. If destroying a large quantity, use a funnel to make your life easier. Viola, pills destroyed.
