    I don't have any problems with this programmer , I used it many times and it has a high performance , and you can set config fuses using programmer software or from PICBASIC , and here we add them using picbasic so it's updated automatically in programmer software
    I will attach the configuration fuses photos

    ' Pic Configuration
    ' =================
    asm
    __CONFIG _CONFIG1L, _PLLDIV_1_1L & _CPUDIV_OSC1_PLL2_1L & _USBDIV_2_1L
    ; ; ; USB clock source comes from the 96 MHz PLL divided by 2
    ; ; [OSC1/OSC2 Src: /1][96 MHz PLL Src: /2]
    ; No prescale (4 MHz oscillator input drives PLL directly)


    __CONFIG _CONFIG1H, _FOSC_XTPLL_XT_1H & _FCMEN_OFF_1H & _IESO_OFF_1H
    ; ; ; Oscillator Switchover mode disabled
    ; ; Fail-Safe Clock Monitor disabled
    ; XT oscillator, PLL enabled, XT used by USB

    __CONFIG _CONFIG2L, _PWRT_ON_2L & _BOR_ON_2L & _BORV_2_2L & _VREGEN_ON_2L
    __CONFIG _CONFIG2H, _WDT_OFF_2H
    __CONFIG _CONFIG3H, _MCLRE_ON_3H & _LPT1OSC_OFF_3H & _PBADEN_OFF_3H & _CCP2MX_ON_3H
    __CONFIG _CONFIG4L, _STVREN_ON_4L & _LVP_OFF_4L & _XINST_OFF_4L & _DEBUG_OFF_4L
