Well, I feel it's worth the money, but I'm a voracious sponge when it comes to learning how to do something myself instead of relying on a supplier. Same with any gaffe card or gimmick, love to make them, but I also have the time, patience, and desire to put the time in and enjoy that sort of thing. Some folks aren't wired like that, or don't have the time to invest in what amounts to a craft on its own. If you think you would enjoy learning and making flap gimmicks, it's on point and feel it's worth the money, in fact, a value.
That said, there are a few things I would have liked to know going in before buying it, like:
It is fully subtitled, as Hondo is Asian speaking in his native tongue and there is no English voice dub. Doesn't really need it, but when learning the many subtleties he's teaching, it requires (for me anyhow) initially looking up at the video more often than would otherwise be necessary if it were in spoken English to view the subtitle, rewind a bit, etc. The subtitles are for the most part clear and well translated, so the info usually there.
There is only one camera angle throughout most of it, it's of mediocre quality, and that can be again problematic for details. I find mtself pausing, focusing, rewinding, etc, a bit more than one with higher quality video and more camera angles and more quality editing would require.
He also is specific on brands and models of some items, and completely vague (subtitles made this even more problematic) on others. Particularly thread. Woefully inadequate info. I'm going to save everyone some time and money here and say to just look for and purchase "Prym". If you buy the video, you'll know, and save yourself the aggravation of buying 5 different useless items to get to the one required.
Lastly, be prepared to spend some significant time and money gathering the items required to produce the end products learned here. (I'd say another $20-$50, depending on what you may already have). Finding the thread needed was the worst waste of money though. I spent more on unnecessary and un-useful threads that wouldn't work until I found the one that did. I gave my vague PSA above on that, so if you pursue this, that's the one you need.
Overall I found it to be of value and worth the money. I enjoyed the detail he went into on technique and varying end products you can make. Lots of little helpful and clever tips one wouldn't find in a book. Hondo did a great job on this and despite a few minor shortcomings, turned out a great tutorial with a wealth of specific useful techniques, methods, and tips for producing flap gimmicks and how to use them.
Hope that helped!
