Adapters that you see in the photo:

• GQ-4X GQ-3X | WILLEM 3in1 PLCC32 to DIP32.
• GQ-4X GQ-3X | JTAG & SPI in circuit programming adapter | ICSP/ISP MODE ADP-056
• GQ-4X GQ-3X | WILLEM ADAPTER MCS-51 / AVR + PLCC44

My personal considerations:

This is a great programmer and certainly more stable of the classic Willem (parallel or usb). I have tried to program some EPROM and FLASH without problems. The power supply via USB is very stable and accurate.
