I bought 3 pieces of these sticks. We use it for a long time and have had no problems. However, there are users that are very negative these sticks. I can not explain the fact that there are dealing with an inexpensive object, which is the same or similar CPUs manufactured only. The best electronic components are also sold at high prices that are worst then the cheapest. If you opt for the cheapest, hoping to luck. I am lucky and was rewarded with 3 well-functioning sticks. The fact is that the choice of formatting (FAT, FAT32, NTSF, ....) plays an important role in the exchange of data between multimedia devices. TV, satellite receiver, Blu-ray players, etc. are often not compatible with Windows or MAC OS. If I'm not mistaken (please correct if wrong) the devices have mostly been playing as any operating software Linux. Linux (that I know of) can read from only the Windows FAT / FAT32. The 32-bit addressing allows only up to 4 GB of disk describe to / read. Greetings! Chfo
