I recently decided on this castle because it offered a fantastic price-performance ratio. My expectations were not disappointed. It seems to be very safe, high is nothing to complain about. Only at the first seemingly complicated handling to get used to, but it's quick. The loop cable can secure the front wheel. For a further securing of the saddle, should the 'Kryptonite Schlaufenkabel Kryptoflex / 76cm dazubestellen. Then I thieves seem really well parried;)! All in allem- a recommended product!
(The support I can not judge because I do not use them.)
