Having worked with Gustav I know why he has only positive reviews. Gustav helped me set up my first Mikrotik router to fulfil my subnet separation requirements. I sent the same request for offer to five different sellers and only Gustav was diligent enough to ask if I had any other routers/switches in my network. Not only did he provide the configuration, he also explained everything to me, so that in the future I can reconfigure the router myself. Gustav was very patient, offering me as much time as I needed and not rushing. Gustav's English is very good, so there was no problem in communication at all. I wholeheartedly recommend Gustav if you need assistance with your Mikrotik router.
