Instructions not clear. Read reviews to find clear instructions
Very sensitive once armed, be careful once batteries are ready. Can go off easily while storing prior to fitting.

Very very loud
This little beast is a must have for motorcycles or bicycle owners. It works very well.
Yvonne Rose –
Very easy to fit
I used the tie wraps to fit it as it will need to removed to change the battery and the speaker is on the front and the battery compartment is on the back.I fitted it to the tailgate of a truck rear canopy. The tie wraps were long enough to fasten the top one round a tailgate piston case and through a cable above to stop it sliding down. The second tie wrap was fasten just round the piston case.Impressive as it gives an audible bleep as soon as the key is put in the tailgate lock and the alarm fob will deactivate it through the glass. Banging on the tailgate will activate it, so any interferance with the back will activate it which is what I wanted. Only took a few minutes to fit and the controls are easy to use.

Very loud if unobstructed
Very loud but 1. Put your palm on it and it gets muffled. 2. The arm and disarm beep is weak and cannot be heard from more than a short distance.I used to have a different bike alarm. Whenever I wanted to check on it’s security I could hear the beep at the press of a button from over 150 feet away in heavy traffic and indoors.This has to be hidden otherwise it can be silenced. The problem is that hiding it inside a bike reduces it’s volume and nobody takes any notice of alarms especially if they are not very loud.It may be best attached semi- externally but in a place a hand cannot reach so it sounds at full volume and cannot be easily removed.

Great little alarm. Bought it to mount inside my kayak for when we stay overnight in a hotel when traveling. Kayak is locked to a trailer but this alarm is added protection that will alert you if the kayak is moved.

This product prevented theft of my security camera! I saw the thieves outside my house and immediately called the police. The thieves stole the camera while I was still on the line with police. The alarm, which I only attached to the camera a few days prior, starting ringing straight away and they couldnât get it to stop because every time they touched it it started ringing again. The police came straight away and it was not hard for them to locate the camera!

Might be a little bit of a premature 5 Star Rating but so far so good.I mounted behind Headlight and Front Rack on a D Series Ariel Rider. (Pic Attached.)Cosmetically the Fob and Device are basic, plain and look durable. It functioned out of the Box. Came with Batteries. The Fob is nice and shiny with Plastic Controls but look Like Stainless or Chrome.The Device is Loud. Chirps Just like locking up your car. Didnât really check range from controller to device, guessing ar least 30â.If you bump the Bike, a Loud Short Grunt-Like Burst Occurs and it has your attention.If you raise Bike carefully off the Kickstand you get a similar attention grabbing sound that is 3 times as long, just as loud and a bit startling.Move the Bike a couple feet and everyone is looking your way because youâre holding a bicycle with an annoying eardrum piercing sound that Iâd stab myself in the eye with a fork to shut off.I turned it off before it turned off every time so I apologize not being able to answer âhow long it screamsâ other then âLong EnoughâItâs impressive and practice with a small price tag. Good investment to protect your favorite stuff and also cool.

Brought it for my cycle. Was really sceptical about it but works really great. Yesterday got stuck in a heavy rain for 2-3 hours. Both the remote and the device were in rain and I thought they would not work again but it still works. Great product for the price surely recommend it.
