If there is no wind, then very good

I use the front and side window protection for my T4 Bulli and am very happy because it has sufficient size and even with covers when optimally positioned the door opener him. However, a major drawback is the susceptibility to wind, because the blade guard is held on the roof and at the door with magnets. Once it is a little windy, the magnets and the wheel guard resolve slipping. However, it does not fly away altogether because there are 2 inner plates which are clamped in the driver and passenger doors. Conclusion: In stronger winds not recommended, with no wind well!
