    Although the picture shows a Raspberry Pi, there is ...
  

*by K***K on Reviewed in the United States on February 18, 2017*

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.
  

*by A***M on Reviewed in the United States on February 13, 2017*

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.

### ⭐⭐⭐⭐⭐ 







  
  
    Great quality for a great price!
  

*by J***S on Reviewed in the United States on February 2, 2017*

This was a great purchase! I couldn't be happier with the quality of the product! Having noobs preloaded made this a cinch to use as well!
