Hello , for long time im waching your forum topics . Im potencial iprog + costumer. With hardware i have no problems , but have some issues and struggling with software, especially with SMART keys ..TOYOTA LEXUS SUBARU.
But there is one problem , i dont see clear pricing. One day you selling it for 700 dol. then 1200 dol.NEXT -   for some time it was out of sailing ?AND  now its 500 dollars. why prices here so unpretictable ?
