Doberman Security Portable Briefcase Alarm Review

I sent this email to the support team on January 15th. No reply yet Hello: I bought this product from Revain. After checking, the alarm does not sound continuously while driving. It only lasts about 3-4 seconds and stops despite continuous movement. Please inform. Many Thanks.

If I could give this product zero 0 stars I would, but of course I have to give it 1 star. I bought several (7) of these briefcase alarms and after 3 months all 7 stopped working. I thought they would be very useful in the office and when traveling. Biggest crap buy ever! I want my money back. TERRIBLE!

Incredibly bad. After my wife's purse was stolen from a restaurant, I decided to invest in 6 of these devices by ordering them without reading the reviews first (breaking one of my basic rules). You are not working. that is, if a shy "beep" isn't much of a deterrent. I tried to shake, spank and verbally abuse her but to no avail. Q: Why are these poor quality products still being sold?

This device does not give a continuous alarm after arming. Sometimes he squeaks shyly, but other times he doesn't even do that. There are too many other things not worth listing as I don't want to spend more time on them. One thing that should warn potential customers is the price. A device that retails for less than $20 would be a piece of junk. I foolishly ignored this obvious precaution. Think about it and then DO NOT click the buy button!

Cannot use this device. Follow the programming instructions but the result was not as expected. That issue aside, the sensitivity of the device isn't set properly so I have to beep if someone tampers with my locker at the gym. My locker was broken into earlier. This device seems to beep for more movements than you would expect from someone searching my locker. It's a shame because it's still an unmet need. ps I am an electrical engineer with many years of experience.

If it wasn't the best out there I would give it zero stars. It's loud and efficient, but has a few design flaws that put you off using it. First, it emits a loud beep when you activate it. Second, it beeps every time you press the button to disable it. Third, the device drains the batteries even when it's disabled, so it's likely to be dead by the time you need to use it. Fourth, the batteries require a screwdriver to open the unit to swap them out (wouldn't be a problem if I didn't have to…
