Review on Enhanced Performance: OSOYOO Raspberry Pi 4 3B 3B+ Unleashed! by Pressure Cook

I received an earlier version of this product, OSOYOO Raspberry Pi Starter Kit V2, as a gift. With over 30 years of tech support, programming and a masters in information technology, I thought this would be a good kit to use to learn more about my RPi 3. WRONG!1. My kit did not have the 3 light sensors listed in the product.2. The kit is described as a beginner's product, you will need a basic knowledge of electronics, Linux or Windows and C or Python.3. The class is full of grammatical errors.4. Hyperlinks and command statements have obviously not been edited and this is not an apology.5. The diagrams are not clearly explained. Lesson 12 clearly shows a DC power cord that is not listed in the Hardware Setup section and is not included.6. The instructions are incomplete, inaccurate and full of errors. Link to jumpers with no explanation between MM, MF, FF. I noticed that Revain doesn't sell the version I received. But judging by the description of this product, the RPi 3 Zero W starter kit has the same lessons and the same components as my kit. I sincerely hope OSOYOO fixed the mess that was in the old set, if not. DON'T WASTE YOUR MONEY AND TIME!
