Portable and security work

First of all as soon as you put the new batteries make sure to close the cover then open it again and close it I thought mine was defective but after doing that it worked perfectly. It’s super sensitive to motion and what’s cool it can be controlled to be less sensitive if you want that. Perfect for doors and windows! It is loud but I do wish it was a bit louder in my opinion but perfect for the money!!!

I compared this to the popular round window/glass alarm and this is pretty much similar except you can arm it remotely. To decrease sensitivity even more, you can double up on the double sided tape to absorb the impact therefore help decrease sensitivity. Besides the remote and angle sensor, there's one more difference worth mentioning. This alarm has a two stage activation (warning/full activation). The first stage or warning stage, the alarm will activate for 3 sec, then the siren will be deactivated. The alarm will continue to monitor and if the device is bumped again within 10secs, the 2nd stage is activated and sound the alarm for 30 secs. After 30 sec, the alarm will reset itself much like any other alarm in this category. Siren is as loud as others as well.This little nifty alarm is worth every penny. The plastic does feel cheap but it's adequate for my use. I'm using it on my garage door. The battery door is difficult to open due to the lack of raised plastic so your thumb can grab onto but can be easily solved with something flat like a flat head screw driver. The battery life is to be determined as time will tell but after messing around with the alarm for a full hour, the battery dropped from 1.56 to 1.54 volts. Also, batteries (2 AAA) are readily available compared to those hard to find button batteries other devices require.I may get the water proof version to use on my fence gate. Perhaps the seller can send me one as a thankful gesture to this wonderful review (wink ;) Hopes this information is helpful for anyone looking at this item.Included instruction is a little hard to follow but if you can read been lines, it's pretty simple. This alarm is fairly simple to operate just like any typical key fob really. It's understanding how it works and the mechanics of the sensor is what determines the success of the product. The sensitivity adjustment is the only thing you need to adjust and this info is not included in the generalized included instruction. It's better to refer to the instruction provided in the information block or under questions and answers but... it's a little misleading or inadequate when it comes to setting the sensitivity.Follow the provided directions to enter and adjust the sensitivity. It's fairly simple really... with the alarm deactivated, hold the off button for approximately 6 secs but you don't have to actually count. Just watch the blue led on the remote to come on and then turn off for a sec or two then come back on but again. You can release the off button at this time. To adjust and move through the ten sensitivity levels, just press the doorbell button (bottom button with a picture of a bell). A beep will sound to confirm each level. The most sensitive setting is represented by a long beep. All other levels are confirmed by a short beep. Here's where it's gets confusing.Just remember, when you hear the long beep, you're at the highest sensitivity setting (say level 10). Every beep after will decrease the sensitivity by one level...so think about going from level 10 and going back down to level 1 where it's the least sensitive to vibration and bumps. To set it to the mid range, listen and find the long beep first. Then press the bell button 4 or 5 times. Press the off button to confirm and exit. To set it to the least sensitive setting, again... first find the long beep. Then press the bell button exactly 9 times (9 short beeps). If you hear the long beep, you know you went too far. Just remember to confirm and exit by pressing the off button. The led light will turn off.To recap, the long beep is the most sensitive at setting 10, and the least sensitive setting is just before the long beep, at 9. The layout of the setting is a bit confusing and I believe this is why the product is getting negative reviews of it being too sensitive. I've check the levels and sensitivity levels are set accordingly but the alarm must be mounted properly. Due to the design of the tilted sensor, it's ideal to mount the alarm flat (horizontally on it's back) or standing straight up vertically on it's bottom or top sides (the round speaker locate at the front top side). The angle sensor works like a leveling bubble but uses some type of free rolling ball or some sort and if the alarm is tilted, the ball will roll to the end and set off the alarm. The alarm must be mounted so the ball stays in the middle and away from the end to work properly.Hopes this helps for people looking to buy this alarm or help dissatisfied customers better understand how the alarm functions.

I tried this on my van since the sensitivity was well rated. I wanted a quick system prior to installing a permanent system. Terrible sensitivity!! Someone can open your door, get in, close the door and it WILL NOT alarm! If they get in and SLAM the door closed, it's OK. It needs to be within 3 feet to actually work! I will say, the remote works well [for me, about 6 feet] & the alarm is quite loud!. It's a product that I can't recommend for a situation like mine. Maybe it can work for you. I'm returning mine.

great quality product / design / remote control access / Not alert alarm even with any 200 lb jumps / vibrations / Not / activate the alarm at all / maybe with direct product slaps / require to use remote control / manual / for alerts /

This product takes two AAA batteries. I put rechargeable batteries in the device and it works fine with them… if the alarm is going off reasonable often, then this is the way to go!The alarm is surprisingly loud! Nice deterrent… mainly because when the alarm goes off the person doesn’t know that it’s not alerting someone’s phone of the break-in… so OFF THEY GO!

Works well it's not a total solution but for 16 dollars it's totally worth it. This is the second time I bought this product. Easy setup as well.

It’s very loud and I like it as a simple door alarm for extra awareness. However was going to place it in a vehicle and it did not work

Very sensitive and very loud👌And doesn't need to much batteryJust if not using take the batteries out because it keeps flashing red light when it's on

I put this inside my car so that if someone got by my motion sensor light, night vision security camera and was still stupid enough to try to break in my car this little alarm would go off and pack a punch. It is loud and annoying and all someone has to do is tap my door or open it or try to open it and it goes off. I am thankful a product like this exists.

It works well, wish it were louder but they do the trick. I will order more for other applications.

I wouldn't want to set it wrong and annoy neighbours.

Loved it
