We are not using this item as a doorbell, but actually using the unit to deter sparrows from nesting in a particular location - we have the chime portion mounted outdoors and can press the button to scare away the undesired birds when we see them thinking about nesting in the bluebirds' box.

Very sensitive unit, even a squirrel or leaves blowing will set it off, which depending on your needs could be good or bad.

Unit works well, mounted about 3 feet off the ground and facing down my driveway, about 60 feet from the inside receiver

anyone know of a good unit that works outside from the git go?

Now I have my main plug-in doorbell by my front door and this useful, portable unit in my conservatory

It seemed to work at first with some false alarms in there but after a week or so the unit quit working.

a day;).The unit does work, well, at night, when it isn't affected by the wind

The sounder unit looks quite smart and comes with a stand

It doesn't t work good in the driveway because every time the sun goes in and out the unit goes off not good for outside

At night the unit is put on the blinking light thanks to the deer who walk past it at night and sets it off

This would be a better unit with battery back up.

and as this unit doesn’t plug into the mains its very economical to use

but once I had mastered it, its tight and secure and the unit stands on my desk, or bedside table, or kitchen counter and looks very nice indeed

This unit works well and is an inexpensive method of giving one a heads-up when someone is approaching down a long driveway

I used it successfully for 6 months when it had a problem, but 1byone Customer Service was excellent in helping me and even sent me a replacement unit free of charge once we determined that was needed.

The unit has not failed to operate as advertised since its installation

This unit is very loud on the highest volume setting so particularly good if you have any trouble hearing a bell

Unit is protected from the wind, so it's not actual physical motion

Both units seemed to work great when we got them placed the first night.

I don't know if I just got a bad unit, or not, but was unable to successfully communicate with the manufacturer, so I chose to return it to Amazon.

Tested the unit closer and it worked fine as well as checked the outlet that I was plugging it

I HAVE A DEFECTIVE UNIT

Easy to use, just plug the main unit inside, and place the sensor anywhere you want it to sense motion.

So, overall, the unit works well, but I wish there were more short notification tones to choose from.

I liked the fact that this unit has a variety of sounds, volume, and flashing light

Also, compared to other motion detection alarm that I have evaluated, IMO, I find the 1byone unit offers more flexibility and option in terms of volume control and tunes; the sensor is quite portable with decent range, so I can move it to various location as needed.

The unit was easy to assemble, though I might suggest that the sellers have someone with a better knowledge of English proofread some of the instructions.

I mounted it high enough, thinking it would not pick up animals but this unit is very sensitive

and so on … this is invaluable to me already, I’ve been carrying it around all day, up and down stairs, even to the bathroom, its great!The push button unit has a rubber ‘waterproof’ button (sensible as it rains a lot here) and it states in the instructions that the battery in it will last 12 - 14 months

I got a response back from this seller and we realized my unit was bad and they refunded me the

unit is way too sensitive.

Previous alarm was made by this company & both units used batteries and worked great for a long time so felt OK when ordered.

Only con if you losing power U loose connection with transmitter [just relearn the unit with transmitter], but would still buy it again!I use it so I can close back door during winter , when it chimes to let dogs in

They always work for a few minutes then one unit stops working

I finally broke down and bought a more expensive unit (from Amazon) that is made in North America) and it works wonderful.

This unit is VERY sensitive.

This new unit is great

I highly recommend this unit!

This unit only worked a few days before stopping to work properly

this unit gives you regarding the chimes

ok I disposed of the box and othedr items and the unit started alarming all of the time I REPAIRED the units relocated the transmitter to 4 different locations it still alarms I would definatly not purchase one of these units if I really needed one to work

I could not find any place I could put the sensors that the units did not produce false alarms.

This is a easy to operate and well designed unit.- battery operated- good volume range with three settings and the top setting is a nice and loud 85 dB- as well as the sound it also can be set to flash, or flash without the sound

I am going with a more expensive, better built, and longer distance unit.

At this point, I would recommend this unit over the Chamberlin, but I have only had it for a month....

and then then the units themselves would die.

This is a great unit

Remote unit is too sensitive for most environments outdoors.

Great unit, the only issue I have with this is that it is so sensitive that when it is windy outside, or if it detects a leaf, bird or any small object, it goes off... sometimes over and over

there are LOTS of chimes to choose from, the first one is just a standard ding-dong style, but the rest are all more jazzy tunes!A good value unit that is easy to operate and gives lots of options

replaced it with a much more costly unit and it was worth the difference.

One unit didn't work at all

This unit only worked a few days before stopping to work properly

Yet, the same unit will work 100% and very reliable in my home

the unit that plugs into the wall just quit working for no reason.

u wont be disappointed

Doesn't seem to drain batteries quickly (I *really* appreciate not having to deal with changing batteries frequently...)
