Is 1500 rating in puzzles good?

The answer to this question depends on the platform you are using. On Chess.com, a puzzle rating of 1500 is considered good, and it is typically higher than other ratings on the site, with a difference of around 400-500 points.

Puzzle rating means nothing however high it is. High rating higher puzzle rating.

Exactly. Especially with this mechanism that gives you a positive score even if you guess only the first move ( in the real game you are punished if you don't play the whole combination correctly).

I'd say that these high ratings, which we can all achieve quite easily, are meant to push us to solve more and more, by giving us the illusion of having great tactical and calculation skills...

Let's solve these puzzles because they're fun and they're a good workout, and let's forget about their useless rating.
