Krevia Security Alarm Metallic Lock System | Waterproof Black Anti-Theft Siren 110DBA Alarm Anti potong Padlock for Universal Use | Thickened Shackle Lock with 3Keys(1Pcs) | Black

One best lock i purchased for my home.....The alarm sound is very loud and will help to secure any place....it build quality is also really amazing....Must purchased item....i going to buy more....for sure.

Good product

It will definitely scare the theif and disturbing people, just prevent water going into it. It has decent alarm sound but it would be great if company provides more than 125 decibels sound.Edit - it stopped working after six months and i changed the battery multiple times but still it's not working. The metal inside it catches rust very frequently and thus power supply is not smooth. Many time i had to clean it but now its totally damaged and works as a normal lock.Edit: Today is Diwali and it is making purrrrr purrrr sound continuously some what like battery is low but it rarely sounds so i don't think battery is dead so soon. Anyway it has started showing problems now let's see how much time it will last. I will replace the batteries and check it once.Edit: Today is 6th November and i replaced the batteries yesterday but same wierd sound was coming which proved that batteries are not low and the device is not working properly but after 5 to 6 regular attempts and some external shock it again starts working. If sound will stops then i'll use it like a normal lock or i'll show it to a professional electrician and get it repaired.

Though the alarm sound is high, alarm goes off during shaking and while crossing speed breakers and it has become a nuisance ! Because when u park the bike the alarm will go off when the bike is shaken.. So I removed the battery.,It would be good if the alarm is set to go off if someone tries to meddle with the lock seriously not just slight pulling !

Most active lock that does its job.Initially it was a little difficult to understand but once i read the manual on the cover it bece easy to set it up.This is really advanced lock that you may have to pay atleast 3-4 times. This lock at this price is a steal.The best thing i loved about this lock is the alarm system.Unbeatable value for money. I am convinced this is really so good

Good

Does not work. Even when the lock is moved

I bought it For my Bike and im using it very good and easy to use lock.This lock is very strong and made of heavy metal.Looks also very good I Like this.
