the product is excellent to put in my briefcase. It is highly recommended. It's great to have on your keychain when you travel (Posted on 8/3/11)

Pros:- The technology is awesome
- It works well
- You can set the range (which goes amazingly high)
- It has two functions; one will alert you when the transmitter comes close, and the other one when it goes out of range (both are affected by the range dial)

Cons:- It's very loud, and it vibrates strongly. While this can be a pro, the user should be able to choose the level of "security"
- Battery powered, of course, so you can't leave it on 24/7
- Sure, it's priced relatively high
- Those blinking lights!
- Can take some time to find the transmitter (=annoying alarm)

Bottomline:A good product to ensure your "product" wun be lose or etc, irregardless what ever you wish to protect against thief or "self" run..
*highly recommended to get at least 2 sets if you intend to do the same as me.. *It's never safe when you thought it's alright, dun regret until you lose the "product" (Posted on 5/11/11)
