This pill splitter is better than another model that we have, because he has a wide blade, with one bigger, harder tablets (moreover without dividing lines) can be halved. Unfortunately, the parts of such work "harder" tablet is not optimal: The halves are different in size and often it is crumbling (but it crumbles less than at our other Tablettenteiler!). Better he shares little tablets with pre "punched" dividing lines. One must make sure that you the tablet previously precisely centered inserts - good guide rails are available as a guide - and then turning a blind quickly GANZ with force so that the two halves of the divider snap the shutter. You can keep the rest of the tablet in the unit, but not air-tight and it may, I think upside down crumble even out, so we leave the unit are only horizontally. Unfortunately, the guide rails construction is very sensitive and easily broken. One has the plastic construction for Tablettenzentrierung simply leave them alone ... otherwise it goes faster than you think broken. After all - this division we can share certain tablets at all. The other factor is of no use to do so. Unfortunately schedule "loss" when it does not work the tablet to share correctly (with large, hard tablets without dividing lines). It is medically unsafe well to take the crumbs that are left ...? Actually, it is supposed, says my pharmacist anyway share only tablets that have dividing lines and that are explicitly by the manufacturer of divisible. Sure the device will also work better. Overall, I'm satisfied, even if the device better (more robust) is likely to be.
