I've had this handy little device nearly a month now to help me split and crush pet medications. The pet meds are very similiar to human pills. This device has easily split pills of multiple sizes cleanly in two and ground the pills into a very fine powder. Although it's made of plastic, the parts are sturdy and built to last. I had a bit of difficult getting the twisting crusher to twist into the grooves properly, but once I got the hang of it I can now twist it correctly each time. I definitely recommend this product to anyone struggling to cut pills with a knife or crush pills crudely with a spoon, this device will make these jobs much easier and at a great price!
