Unfortunately I am not satisfied with the HiWinS from BlueRoll.
1 Rail/Carriages Combination works perfectly, the other four work, because the Carriages does not move one millimeter
when I straighten the rail. I have a cheap China combination here, that works fine.
Bluerolls has also written to me that these are heavy-duty carriages and they want to send me new ones, the right ones.
The support was not so bad. Have responded quickly and not even trying to convince me that I have to clean and lubricate first.
I have now received a tracking number and the Carriages are supposed to be by express next week with me ... Let's see if that gets better.
If everything works then so much the better and from me kudos to the support.
