Poppstar can I recommend. The stick was OK as long as it worked. After 1 year my stick was then no longer recognized. The complaint process takes place now only two months, the stick is for five weeks at Popp PC. I've tried dozens of times via email and phone, I was often promised to get an information within 48 hours. Unfortunately, this never took place. Now have turned me on my package, whose portal bears I bought the stick.
