The first compound is compared to the Samsung glasses a bit more difficult (it must be pressed for more and it needs before several attempts).
Once the connection has been made once, the glasses then connects without problems with the TV.
The comfort is good and the accessories are complete: besides the manual is still a protective cover, a cleaning cloth and a USB charging cable (microUSB) at.
I now own two of these glasses and keep the Samsung glasses only as a "reserve" ...
Important Note about compatibility:
The current compatibility list for these glasses is incorrect or incomplete.
It was apparently with the list for "3D Eyewear - Universal 3D Active Shutter 3D glasses by PULOX FOR SAMSUNG (LCD / LED), PHILIPS, SHARP, TOSHIBA, SONY, PANASONIC, LG, MITSUBISHI (PLEASE PRODUCT DESCRIPTION for compatibility NOTE)" reversed!
These glasses (infrared & Bluetooth) works in the case of Samsung devices with both the C (IR) as well as the D- and E-series (BT)!
In contrast, the pure infrared version can not work with the newer D- and E-series devices, this is, however, so in their compatibility list!
I have already pointed out two dealers, it has not been changed so far, however, a pity!
