Question: Is Special Lite insert approved by US Postal Service?
Document: This is a flimsy insert for a specific mailbox that is made by the same company. It is certainly not worth $60. You could cut it open with a can opener, or a good pair of metal sheers. Glad they took it back, because it is not even a full box like what is pictured. There is no bottom, and no back to it.
The deception is wrong. The item listed the size of a normal mail box. I measured my mail box and matched it to the decription listed and guess what its corners is 1/4 of an inch off so this item will be too small for the next size mail box. The company that made this item needs to hire a person with math skills to measure and post it as its actual size. I will never buy anything from this company again. I feel like I've been burned by deceptive marketing strategy.
Product was actually damaged (a big dent on one side), but I didn't feel like messing around with another return. (The previous one I ordered was too narrow (7.25" vs. 9"). Works fine, easy to install and so far no stolen mail. I gave this a 4 star review only due to the damaged goods. Other than that it works great!
Nice quality lock, but the rest is thin sheet metal.
My order was delivered in new condition, easy to install, it was exactly what I was looking for! Perfect for my standard curb side mailbox. Helpful hint - measure your demisions before ordering - there are many on the market with different sizes available.
My comment is about locking sleeves in general. My previous mailman was happy to do the logical thing, put the small envelopes in the locked slot and put the junk mail on top of the sleeve. The mailman I have now will only put mail on top of the sleeve even though everything except junk goes through the slot easily.
I had my bank documents stolen right out of my mail box recently and had to change all my accounts because of it.So, I researched all available locking boxes and settled on this one because it fits INSIDE my own oversizedbox and still has room for 9x12 manila envelopes to go out, which I do often!I am very pleased with this box and feel my mail is safe now even if these scums do theirdrive-bys and try to grab identities right out of people's mailboxes!
Answer: no
