Question: Mailboxes face the street, away from the house. Ours is in a brick column. If "line of sight" is important, will it work?
Document: Pros:Works fairly well. Mail-waiting reminder is very helpful. Loud beeper can be heard all over the house. Price is right.Cons:Loud beeper can be heard all over the house. Range not as great as hoped for. Works about 90% of the time.I'm getting about 60' of range from it in my wood-frame house. I had to put the receiver in the living room at the front of the house since it did not work reliably when moved further away.
It's also nice to NOT go across the street and find that the mail is not there yet. It's been a very cold month in Minnesota (-30) and I didn't think it would work in the cold - but it did.
Mailbox is across street, yard, and opposite side of house and still works great. As has been noted, speaker is super loud. I'd imagine if you had a big house this would be a plus.
We have had mail theft issues in my neighborhood. I liked the feedback on this alarm. I was skeptical but it really really works. I have had this in my mailbox for about 1 month now. Easy to set up. My mailbox is plastic so I didn't use the screws to install - just the sticky back tape. The alarm does NOT have a volume control - that would be the only downfall. It's loud. I work from home so I can hear the alarm anywhere in the house.
works great. It's 200 feet from the house.I have been using it about 1 month. When the lid opens, the alarm goes off in the house.
This is a great item if your mail box is like ours. Out of sight & alarm is loud & clear & works great. Would recomend to anyone to purchase this item. Great product...
i mounted it high up on the door to get the most movement out of it but same results, then about a month later it wont work at all unless its real close to unit, like 20'. batteries replaced same results. i would return it if i could. save your self the money.
Got this as a fathers day present and I cannot wait to give it to the lazy old guy! (just kidding)I would buy one for myself , but I have a community style box, and its more than 300 ft away.Could use it for any box/storage that opens top down like a mailbox (as that is how it is triggered)...
This is very easy to install. Our mailbox is at a distance from the house, so I needed to lengthen the short wire antennae and make sure it was not rolled up but extended the full 18 inches length. It IS a loud alert, but should only happen once a day. The light stays on until you reset it. Our mail is now delivered at random times - from about 2 pm to 8 pm - so having the alert is a huge benefit. Well worth it for me.
The wireless mailbox reminder saves me unnecessary trips to the mailbox checking for delivery. My mail person has varied delivery times . . . sometimes as late as 6:30 in the evening. The Wireless Reminder device was simple to install and works flawlessly every time in all kinds of weather, even in subzero temperatures! The alarm sounds loudly in my house when the mailbox is opened and the LED lamp on the receiver stays on until reset as a reminder that the mailbox has been opened.
