Nokia BH-700 NOT!

Bluetooth ear pieces such as the Nokia BH-700 are available on okay. So are their counterfeits. How do you tell them apart? Here is my experience:
Counterfeit #1:
1- Purchased directly from Hong Kong. It arrived with a Chinese language owner's guide, which wasn't a surprise considering the source. It had the correct accessories.2- Worked for the first few days then would not take a charge. 3- When it did work it had a very static filled signal. 4- The blue LED never appeared. Red and green were the only colors that appeared. Blue was supposed to appear upon connection to my phone. 5- Sound quality was no where near as nice as the BH-200 it was replacing. 6- LED illuminated the entire top third of the device through the thinly painted plastic. On my genuine BH-800 the LED is a pencil point and not at all diffuse. I am assuming that Nokia LED philosophy of what an LED should look like applies to both items.7- The second time I attached the charger the red led flashed and then nothing. Unit is dead due to malfunction of the charger receptacle circuit board interface. I pulled the thing apart and can make it charge if I hold my thumb on the circuit board. I have better things to do.
Counterfeit #2:
1- Bought this one from a seller located in the United States. 2- Looks exactly like the one from Hong Kong. 3- It had a Chinese language owner's guide, a non-original and also non-fitting neck strap attachment. I didn't expect this from a New York seller.4- This unit failed to show the blue LED upon connection. 5- It had the same, or worse, static problem. 6- The other reason it resembled the first counterfeit is that it has the same serial number! See the photo below.

Both of these BH-700s are bogus!This is a genuine unit
