All 5 pieces are working great. Paid around 10 euro for 5 which is very cheap. They are also genuine! One picture are the 5 chips, the other 2 are the ATmega in action. One running on 5v, another on 3v, both with a 16MHz crystal. Although 16MHz on 3v isn't officially supported (out of the "safe zone"), it works just great. It's basically overclocking your setup by around 20%.

Having the bootloader pre installed should save some time and headaches.

Product very well packaged . The bootloader is already installed. The chips works as expected.

Very well packaged with foam. Well done. It's good to see that some items are taken care of when packaging.

I have been building projects based on the Arduino uno but on a controller of my own design. These microcontrollers are perfect as I can program them in my Arduino due to the Bootloader already on the device, and then transfer them to my project. These devices work out to be about $4 AUD, So they are awesome value for money,
