Not very good.
Cheaply made (in China, of course). Not nearly the quality of a similar pill holder I've had for years. It is hard to line up the threads on these to put the cap on, and the metal clip on the cap looks like it will come off easily. On one of mine the metal clip swivels, but not on the other one. I expected more for the price. We'll see how long they last.
