The fact that this part of "tons" is, so I would have been open in this strong form not counted. Of course, quality has to be, but with such an extremely heavy part, I would have never expected. To ride alone on a slight hill is effort pur (and no, I'm not lazy or even unsportsmanlike - far from it), it is then time gain altitude that goes quite in the thigh or in part (Bisamberg-asphalt road uphill to example) no longer possible, even not when the child is stopped, sometimes briefly mitzutreten diligently.
I can - unfortunately - even the very rapid rusting on FollowMe confirm and I think something may in such an expensive part so soon not be.
All in all I would FollowMe-Tandem coupling no longer buy, but I remember back to the Trailgator tow bar and bike trailer. These two parts can be quickly switches back and forth.
Conclusion:
The idea of a clutch is a really, really good!
The implementation, the weight, the quality (keyword: rust) is bad, however.
Combined with item 2 the price is much too high.
