Master Lock ProSeries Stlss Steel Combo Lock

The dials are difficult to turn. Difficult to see. The line to set the dials is in an illogical place, rather than being in the center it's offset. In a perfect world viewing the lock from the from to set the combination this position might be convenient. However in the dark or if the lock is backwards because it's on a chain it's really inconvenient. The dials are tiny and shiny, the silk-screening isn't bold enough to contrast well. If you try to shine a flashlight on the dials the glare from the reflection makes it hard to see. Unlocking is hard to because the dials only go one way if they reach the end so you have to go all the way back say from 9 to 0 instead of just one click. The rubber dust protector is useless, it falls off easily, is difficult to put back. The sides of the viewing port are sharp and hurt your fingers when operating the outside dials. On the plus side, setting your own combination is easy and there's no tool required. However the instructions are confusing.
