I have had one (UPS store box) for more than twenty years—love it.
I think 15 years but the last 12 were consistent.
Very rarely do I have anything shipped to the pad.
There are some exceptions I’ve had to make with a few vendors. The problem isn’t them per se but Stamps.com.
For whatever reason, their software will not understand my UPS mailbox.
I was on the phone with one reseller as they manually typed and after enter, it would flip.
