  • review rating 5  I've found this company using the internet search, so no prior acquaintances or any relation at all - which was kind of a leap of faith, if you will. We had a nice initial meeting and I was offered several solutions for my questions. Basically, after one discussion there I got more information, concerning my issues than for half a year of working with other companies. It is a pleasure to work with this company - they are reliable, their knowledge and skills are extensive and constantly improving. Openness to different solutions is a great plus too. A thing, which is very important to me - since my timetable is really busy - they are fast-responding and fast-thinking. As a result - I am happy to recommend them to other people.
