Summary:
I purchased the the Super Kit because it includes a wide variety of accessories for my sons (ages 13, 11, and 8) to learn to make cool projects using the GPIO on the Raspberry Pi.
We are able to do these projects and more:
Control LEDs
Use an LCD to display a message
Control Motors
Use switches and buttons
Plus many more...

The product title is "SunFounder Project Super Starter Kit.." and the description states the Super Kit "provides you tutorials to learn about Raspberry Pi, designed for beginners (also experienced hobbyists)." However, on the Sunfounder website the product is listed only as the Super Kit. Having used this kit for a few days now, it does not feel like a true "starter kit" and neither does the Raspberry Pi. This is not necessarily a bad thing, just something a beginner should be aware of - the manual and website tutorials will provide you the steps but you will need to use other resources to understand the concepts.
Raspberry Pi,Linux, and this kit are designed for do-it-yourselfers who don't mind learning the basics computing and electronics with minimal guidance. For my kids and I, this is a good thing. Anyone can download a file, accept the terms, and hit next 3 times and have a working application or project, but we wanted and got more.
Although the code provided is written in C we used Scratch since my boys are younger and have limited programming experience. The C code is just copy and paste from the web download but it is much more difficult to follow if you're not familiar with programming.
The variety of items in the kit combined with the manual and web resources make this kit a worthwhile and fun purchase.

So far very good. Good out of the box experience, simple examples all work so far. Software is explained. The only hiccup so far is that the LCD display intensity is very weak, useless. I did adjust the pot on the back of the display, that took if from blank to barely readable.

My grandson and I have been having a blast running motors, making LEDs blink, and generally messing around with circuits. As a long-time electronics hacker and radio ham, I hope he gets interested enough to do some of that on his own, and this is a great place to start. You nee a Raspberry Pi (which I already had) to do the experiments in the book, but there are also places on the web where (for instance) you can look up circuits you can make with the components in the kit and without the Pi (example: a 555-based LED flasher).

Downchecks:

1. The book could do with an editor.

2. I find it hard to read the color codes on the resistors. That could just be my old tired eyes.

3. More importantly, the leads on the resistors are very thin and bend way too easily. I ended up subbing out some of the 220 ohm resistors used as LED current limiters with 1/2 watt models that had sturdier leads.

4. The 5v side of the enclosed power supply didn't work (the 3.3v side is fine). I don't know whether I blew a component somehow and let all the magic smoke out, or whether it came pre-blown, but the voltage regulator is clearly not working. On a 9v power supply the 3.3v side reads about 3.28v on my VOM, but the 5v side reads something like 8.78v. (I fixed this with an external LM7805 voltage regulator, thereby teaching my grandson something about improvising).

The only qualm I have with this kit is no detailed user manual like shown on the sub founder website - I am currently looking for a step by step guide to create and expand on projects using the included apparatuses. Besides that I love this kit and it has a lot of cool parts helping you Learn to code and create.

This is a great kit for kids or adults learning about electronics and the Raspberry Pi computers. There's a nice assortment of sensors. The documentation has a few grammatical errors (obviously translated); however, it's very thorough and includes code in C and Python. I haven't priced it out, but I bet you would spend twice as much if you tried to build this kit yourself.
