Perfect. It sticks in a few seconds and the nail doesn't come off at all. I haven't used any others to compare, but it satisfied me completely. It is transparent and quite liquid. It smells like the classic UHU moment when it sticks everything (conspiracy theory: I suspect it's actually the same product!). This one doesn't have a brush but a nozzle. However, there is also the corresponding one with a brush for those who prefer it.

To remove it, soak your hand in warm water for about 10 minutes.
