Although the picture shows a Raspberry Pi, there is not one included in the kit so it will need it be purchased separately. The SD card was supposedly flashed with NOOBS for a simple OS installation, but with mine it was corrupted and I just got a screen showing a colorful rainbow. Took me an hour to download and install the Raspbian OS...which kinda defeats the purpose of spending $30 to get a preloaded card. Maybe others experiences are different but for me this kit wasn't plug n play.

Not Worth It. Unresponsive.
The kit was packaged very nicely. But, I bought the kit hoping for a plug and play solution. The SD card didn't work, I needed to format it and install NOOBS myself. I emailed the seller and never heard back.In the end, it was more of a pain than it was worth.

Best Raspberry Pi 3 starter kit you can get right now. While you can get everything in this kit cheaper if you shop around but the convenience of getting everything at once plus all the instructions that come with it are great, its worth the price.
