Don't buy, check HIS github or google collab for EVERYTHING that's in this book. NO SOLUTION
Format: Paperback
I never write reviews, but after this book I need to. DON'T BUY IT. DO NOT BUY THIS BOOK. Feels like a money grab. You are literally paying money for NOTHING buying this book. Long story short: GO TO HIS GITHUB AND GET IT ALL FOR FREE BECAUSE HE DOES NOT PROVIDE SOLUTIONS. GO ON GITHUB OR GOOGLE COLLAB AND CALL IT A DAY.
In the intro he makes it seem like you don't need to know much programming or any tbh. He says if you have never programmed you should be able to read this book. HELL NO, I mean yeah you could probably figure it out, but I would not let someone that doesn't know any programming to start with this. I'd probably tell you to learn the basics of python for a week before starting at the very least.
He also makes it seem like you don't need much knowledge of physics. Meh, maybe.
Anyway the main reason not to buy: IT'S ALL AVAILABLE FOR FREE ON GITHUB THAT HE PUBLISHES FOR FREEEEEE. You can also use google collab, which he has up for FREEE. and if you are are a beginner I'd recommend you go off teh google collab, that way you don't have to deal with downloading anaconda and setting up an enviroment in jupyter which I think can be intimidating for a beginner. And this book doesn't really give much help in setting up everything in jupyter notebook.
Also another point. He'll lead you through an example each lesson, but for the exercises he has you working on he doesn't provide a solution ANYWHERE. like why tf would you buy this book? How do you expect to learn with no feedback? You need to search online for ways to solve these problems, which I think is not a bad skill to have, but if you are new to a subject or trying to learn and you pay for a book why can't i at the very least get some solutions. even math textbook give you solutions, because the understanding is that you can make your own attempt and CHECK TO SEE IF YOU ARE RIGHT. DUHH !

Solid Metal Razor
Color: Polished Silver
I’ve been using this for months to clean up for light dermaplaning, and I really like it. The metal handle feels solid and easy to control, which makes it feel safer than the cheap plastic razors. The blades are sharp but gentle if you use a light hand.
It also comes with a lot of replacement blades, which is nice since you don’t have to replace the whole razor and it saves you a ton of money. It took me a try or two to get used to the weight, but now I prefer it. Overall, it feels well-made and works exactly as expected.

Great razors!
Color: Micro Distance-10pcs
Sharp, convenient. I appreciate that they’re a bulk pack! They work really well on both face and head hair, and fit perfectly into my japantools razor.

Fantastic Dermaplane Razor that you can replace blades on
Color: Polished Rainbow
This Dermaplane Razor is great. It gives a close shear and has a nice grasp in the hand, plus it's pretty cool looking! I'm happy to have a metal razor that I can replace the blades on and ditch the plastic throw away type. The ZOMCHI Dermaplaner is far superior. I am pleased with this purchase.
