Review: super !! - I got the KJB just a litte problem with the convertor i used another convertor and is ok we are in europe different current, otherwize is perfect the service of the company excellent they help me with all my questions, it works fine you need just to regulate the frequency and vibration.. the money is worthy
Review: No battery cable or battery pack. - The device is sensitive enough and appears to work well. To really use the device you need something more than a short AC cord. I had to build a 12volt battery cable and buy a small SLA battery to make the device truly portable.

**Q: It appears to not have a battery pack. does it have to be plugged in, and if so, how can it be made mobile?**
A: The battery is housed inside the device. To the right of the antenna theres a plug to charge (9-12VDC), it takes twelve hours to charge for the first charge. Every charge thereafter is four or six hours (double check instructions). The device is mobile. Its a good battery, I've only charged it once, I havent needed it. Maybe a handfull of places I've actually swept a specific area and ive had it for eight months. I wouldnt leave the device plugged in the wall too long after its charged, you'll decrease battery life.

**Q: Is the dd2020 dual voltage?  I want to use this in malaysia.**
A: about the dual voltage for malaysia  I do not know, probably you need an adaptor ( the detector is with an american plug ) but about quality is good, but you know to learn how to use it, at the limit of the vibration and the limit of the soundyou will see when you got it , I got a problem with the charge , I just use another cable for  recharge and was ok

### ⭐⭐⭐ The good and the bad and the ugly of it
*by D***Z on February 8, 2014*

The good: Well made. The case is black-anodized aluminum, not cheap plastic. The antenna is a standard whip as used on portable police and field radios, and attaches with a BNC connector, just as they do. Finding a replacement should be easy. The ugly: The blue LED, which indicates the unit is on and flashes when the batteries are low, is WAY too bright. In fact, it makes a decent indoors flashlight. Unfortunately it is located just above the five red LEDs which light up successively to indicate the strength of a received signal. The LED is so bright that watching the much less bright red LEDs gave me a headache. I placed two colored stickers over it, and it is still too bright showing through those. The bad: While it easily detected my wireless indoor phones when in use and my "emergency 9-1-1" pendant's base unit (which I was not aware broadcast RF continuously and see no reason why it should), it did NOT detect my hobby FM transmitter, which is emitting a powerful signal on a frequency well within the advertised range of this detector. Powering the transmitter up and down made no difference to the detector even when it was right next to the antenna. So, does it not detect FM? FM is just a type of modulation for a RF transmission, and this device is supposed to detect RF emissions. If it does not detect FM, then I would consider it useless as a serious bug detector. Update 3/31/14: I sent the last few sentences above as a question to the manufacturer of this product on the same day I wrote the review. They responded by asking for the make/model information on the FM transmitter, which I provided to them. On 2/20, I wrote them again asking what they had found. The response was that they were working on it and "have not forgotten" me. I have not heard from them since. (Now August. Never heard from them.)
