I have bought this Programmer mainly to bypass the start delay by the Arduino bootloader. With the help of some adjustments in the configuration files of the Arduino IDE, the programmer is working very well in this environment. In addition to the elimination of the delay at the start of the Arduino, this approach also has the advantage that more space for the program remains on the Arduino by the absence of the boot loader. I've programmed the Adruino-Micro in this way and am very satisfied.
