Ear training courses

[tomp86]

Hello everyone. I am curious to know if anyone has had a positive experience with any ear training course, in particular, I'm looking for a way to find a pitch that is in my mind more immediately rather than guessing at the piano keys.  If I guess at the keys sometimes I get it right but sometimes wrong

Ear training courses I've seen advertised include

Piano lessons with Warren $38pm

Rick Beato Ear training $!60 on sale

David Burge Course (very old) $199

Can anyone possible share any positive experiences on these to help find pitches faster and accurately 

Regards, Tom
