Compliant and reliable

Used regularly for over two months with "peripheral" an S4 smartphone and tablet Lg 8.3. Connects very quickly 3g or 4g according network availability. Allows a program in 2.4 Ghz or 5 Ghz (often less crowded). Personally I always maintain 5 Ghz. Battery life is sufficient for several hours (if not foresee additional battery Anker style for example). Obviously depends on network quality 3g / 4g. Two very small criticisms: the screen scratches easily (plastic medium quality) Gold mobile use can quickly forget the precautions at this level. And the protocol provides for automatic connection attempt (logic for saving time) without detection of a map change. After introducing a new data card, I have unfortunately found that 3 attempts Pin codes were exhausted and that the card was blocked (just have to find the PUK :-)). Obvious solution, "but damn but it's course" (communicated very quickly by customer service reactive TP-LINK): Always use the same PIN code for all cards inserted in Lengin data.
