From my research posture correctors aren't good solutions, because they will make be doing the work of your muscles, rendering your muscles weaker - specially concerning on muscles that are already at fault for being weak.

They could be worn for short periods of time, at max like 15 minutes.

You need to strengthen your back and shoulders, stretch muscles that make you curl forward, and you need to be patient... I was very frustrated in the first weeks trying to correct my posture because I wasn't seeing much results, but it just takes time.

Like you're trying to undo years of bad posture in few days it's impossible, your muscles need to gain strength, they also need to rest, and you will need to learn to do proper movements with the new acquired strength and muscle activation.

So I don't think posture corrector doesn't cut it, I'm sure they're very useful in specific situations, but for the majority of people you just need strength and stretching.
