Review on Essential Teenitor Reducers Transfer Droppers by Jihye Rivera

As others have said they leak. To be honest the glass is good quality, thick and solid and they appear to be well made. However, they leak terribly and waste all the liquid you have. If you use an orifice reducer it will create a better seal with the cap and little to no liquid will come out but then it becomes extremely difficult to squeeze the liquid out at all. The orifice reducer is so small that pulling out a single drop is excruciatingly slow. Overall a decent product but they really need to rethink the cap and gearing. A better cap or a slightly larger hole in the hole would have made this product significantly better. I would return them but my Revain return window is closed.
