The unit is smaller than it appears in the picture. It is 2-5/8" high.
There is no provision made for the unit or the magnet to be mounted with screws, only with the foam tape.
The batteries (3 X G13, LR44) come dumped together in a sealed bag which is not very smart. Button cells can touch each other and drain themselves. You insert the batteries by flicking a flimsy plastic latch at the top which allows you to remove the entire front cover. This operation involves disturbing two fine wires which go to the speaker. By battery replacement #3-4 one of these wires is going to break and this thing will be garbage. I don't expect an $8 alarm to withstand much physical abuse but it has to be able to take some or it can not be relied upon to do it's job. I am afraid these could be disabled by anyone wanting to shut them up in a few seconds.
I ordered 3 of these and only opened 2 of them. The first unit would give a "mip" sound every 3 seconds and did nothing else. While the instructions do not mention this behavior, it was telling me that the batteries were defective. The second unit was OK.
The instructions note that if you wish to mount the magnet on the left side of the unit that you may have to move the internal switch to the other side. An odd request which would best be preformed with the aid of a glue gun.
There is enough circuitry in this thing for the claim "Built In Sensor Will Detect Sharp Entry Or Glass Break" to be true but the instructions make no mention of this feature. Also. rapping sharply on an empty glass jar did not sound the alarm so do NOT count on the glass breakage detection feature to work.

Not sure why it's listed as wireless other than there are no external connections. This is a battery powered alarm with a magnetic switch. It uses 3 G13-A CNB button batteries. There's a switch to turn the unit on and off.

This is a good little alarm. Its very easy to set up/use! I mean for under $10 you can't ask for a whole lot more. This item is meant to give you a warning from an intruder and that's what it does. The alarm is not extremely loud so don't know how effective it would be for a larger home.

Although this is small in size, the alarm is quite loud. This is an inexpensive way to deter unwanted guests and sleep a bit more soundly at night. We would highly recommend this product.
