As some have already mentioned, the number of possible combinations for someone who wants to crack the lock quickly reduced to 125. For this you have to draw only on the bracket and first turn at the lowest wheel. One quickly realizes that the number plate can no longer be further turn. Well just see if the number is the display is even or odd. Is it just as is also true for the number of solutions that they will be straight. Is it odd, then ... well you know what's coming .... Analog can this then the 2nd and 3rd wheel out. Is> 5x5x5 possibilities, ie 125. Someone of the castle so crack will therefore need on average only about 63 attempts to the castle cracked - this is done stay per wheel only 5 possible solution numbers.
Conclusion: should this lock pick actually be necessary in average 500 attempts but it needed just 63 attempts. So only 12.5% of the security you want to buy here. The castle is thus about as useful as a lock with 2 speed gears - I think something like this would not even be produced. So clearly: Stay away!
