Any feedback / thoughts on e-collar usage for 6 month old IS puppy?

Looking into ecollars as a way to train our 6 month old IS.

Don’t plan on using the shock, more so just a tone for positive behavior and vibration for behavior correction. He is incredibly impulsive and it’s been a lot for my pregnant wife.

We plan on using him as a hunting dog eventually too which I know this is useful for, so wondering what everyone thinks.
