Expert Reviews

What reviewers liked

Many love this lock for its ease of use and design. Some previous customers have said that this is the best possible lock you can get for the price.
This smart lock gives a good account of itself for its durability and practicality. If you need something to keep the weight down on whatever you’re planning to lock-up, this is your ticket. With its 6-pin core and tough integrated body, even skilled pickers would find this padlock challenging and time-consuming to break.
For under $50, this Stanley CD8820 is one of the best padlocks you can get. The shrouded shackle keeps it protected from bolt cutters. The 6 pins and anti-pick pins make it difficult to pick the lock.
This is one of the best high security padlocks with a hardened steel body, It is resistant to pry attacks and hard to pick due to the 6-pin cylinder.

What reviewers didn't like

While certain customers have said that this lock can be easily picked, the option of upgrading the core mechanism can add extra security to this durable lock.
If you’re set on getting additional keys, this one might pose a problem for you. The Stanley Hardware is not so easy to get additional keys for.
