I do not personally know anyone who has tried this, but from what I’ve read
[someone (batgirl_cdn) wrote about her experience in this forum: http://forum.singaporeexpats.com/viewtopic.php?t=56041; this article offered a few accounts from mothers who have tried this: https://www.nuh.com.sg/news/media-articles_1732.html; a review blogpost by a mother who used hypnobirthing: http://ramblingsofsneakymum.blogspot.com/2011/10/hypnobirthing-in-review-marie-mongan.html], the general take is that pain is manageable, the delivery was also shorter.
Apart from Four Trimesters, you can also consider these companies which offer hypnobirthing classes:
