I have, since incorporation of an engine in the axis in the roller shutter box has not been possible for a Gurtwickler seen that done with some comfort the same. In addition, the strap is directly out the window, so that even a wall, for there are better Gurtwickler of Rademacher, is not possible. This Gurtwickler done most easily with 5 further his service, the remote control, which gives it a great for me (too) high price, I have cloned over priced learnable remote controls, everything (almost) perfectly. Unfortunately, this Rollotron no radio clock, summer / winter time also does not arise automatically, and after 8 hours without electricity all programming is gone incl. The end stops. Although only a few minutes, the reprogram again, but annoying nevertheless, especially when it happens on holiday, is the "Presence simulation" gone. Therefore, a star deduction. Unfortunately, the more advanced features of the series for wall installation (eg radio clock) are lt. Rademacher not implemented on request in this Schwenkwicklerversionen because the need is apparently for this version is not high enough
