It's a simple and deceptive idea which you can use for a multitude of effects. As explained, you can use this idea with any borrowed deck, without any preparation. The video quality isn't the greatest but you can learn the control easily. Really simple for all levels and a couple of routine ideas are included.

First of all the trailer is very honnest. The Newton's Touch is easy to understand and to achieve, but for it to look comfortable it will take a few times to get your hand used to the few easy moves needed. It's not fully angle proof, but there is really not much to worry about. It isn't a trick in itself, it is a sneaky tool that will help your spectator experiencing some impossible moments. It can be used in many different ways from a straight on color change to a sophisticated reveal for mentalism. And it is so versatile it can be used with a totally normal deck of cards as an impromptu effect, or with some preparation in advance to be a part of much more complicated routines. It is a "small tool", but it can add a lot to your card effects.
The biggest limitation seems to me to be that it shouldn't be used too often. Better keep this tool ready but not shoot it at every occasion because there could be some heat upon the method used.
The PDF file is good, the instructions are clear and illustrated by a few pics. The 20mins video's quality isn't awesome but there is no problem following the moves and the jam session brings some cool ideas. The only reason I took one star off is that the audio quality could be better... It is quite unbalanced and even if I'm sure it won't be an issue for many people, english isn't my first language and I had to rewind a few times to make sure I heard it all.
I would recommend using the Newton's Touch, it might seem humble but it sure can get some cool reactions.

Incredible utility! Perfect for so many effects, this method is absolutely brilliant. Another win by Luke Jonas!

Easy trick that makes use of an ages-old problem with cards for the magician's benefit. The handling is simple to learn. Angles aren't too bad. There is a tiny bit of audience management required with a mildly unnatural move and the card box cannot be examined at any time. Other than that, beginners should love this method for many tricks that would otherwise need a more standard force of some sort.

I had the luxury of being taught this by Luke, himself, during a zoom meeting. This effect is so simple to perform, but blows the mind of nearly every spectator. I love this, and I'm sure you will, too!!

This is a really clever and practical principle for a card switch essentially performed under the yes of the spectator!
