Value
Dropped in as a replacement for my old mailbox lock with no problem at all. Pricing was definitely fair and overall quality seems fairly high. If you need to replace a broken lock then this will do the job.

Works as it should...and it was in the BRASS finish.
It attaches and works as it is supposed to. PLUS, I liked the fact that this was offered in the brass finish. Good value for the money.
