I have the castle now about 2 months ago to buy my new bike also once Aldi can be safe in the public eye. The castle gives a very sophisticated look is well made and a bit heavier. The handling is super although 110 cm partially if you have to chain the bike is too short. I think in quiet areas you can use the lock problems but in larger cities in my opinion not. My bike was now after 2 months swiped the lock was sawed normal. The advertised Drilling in my opinion is not a reason to buy as bolt cutters, saws and Flex are used more often than the "intiligenten" methods such Picklock and drill into the castle. A television station has coincidentally also tested said bicycle lock and has the same experience as I do that the lock max. 1 minute hold. Unfortunately, I can therefore only partly give a buy recommendation since each lock with some effort is crackable. But that in such an already priced upscale castle as soon goes disappointed.
