Good UI (good appearance and quality as well). Bad UX (to change the bulb, you have to remove the entire spot, so you have to unclip it from the false ceiling, which is not convenient at all).

The spot is indeed divided into two parts, the base (which theoretically would remain permanently clipped to the false ceiling) and the stem that holds the bulb. Theoretically, this would be the only thing that should be removed when changing the bulb.

In the end, when you remove the stem (screwed), the base is thrown inside the false ceiling because its lip is much smaller than the hole that needs to be opened in the false ceiling to place the spot.... I was really disappointed with the experience. But other spots of the same and different brands that I have purchased do not have this 'feature'... Luckily, I only bought one, tested it, and so I only wasted 13€.
