The instructions are impossible to read on the box, font too tiny. So I watched the videos and followed the instructions. I still need help getting the stupid thing to open. If I can't now, how will I ever open it on my gate?

This is more of a helpful hint versus a review. I got the product I ordered which was the lock with letters instead of numbers for the combination. However, the packaging it came in was apparently for a different model if you see the attached photo. For that reason I was confused by the instructions on the reverse side of the packaging (not shown) telling me to start by setting the lock to it's factory setting of 0000 as there were no 0's (or even the letter O in this case) on the 2 outer wheels. Thankfully, the folded paper instructions, which I didn't notice at first after cutting through the plastic outer packaging, were for the correct lock and I was able to get it open and set my own combination. Now I'm probably just a numbskull for not noticing and reading the instructions at first but I thought I would post this in case someone else makes the same mistake hoping it will save others some frustration. :) I mean after all, this is a Master 175 LCDCD that came in 175 DLHWD packaging!

Update: After 5 months the lock is no longer closes and will open at a slight tug, even without the combination in it. Beyond useless. Bought 3 to lock my outside gates. Within the first week, I was having trouble getting them to unlock. The combo is correct, but will not open. Have to bang it to get it to open. Also, changing one number causes all the others shift as well, so it takes awhile to get the numbers correct. Not made well or for outside.

I purchased these to use outside. They are sturdy amp; just the right size. At first I had a hard time opening amp; closing them. Put WD-40 on them amp; now I am well pleased with them. Great locks!

Love this lock for my backyard gate. Strong and predominant. No fooling people that the gate is now locked and secured.
