Be careful with the product. It is indicated that the model is C-U0007 but they actually send the C-U0010. The C-U0007 has a Nordic chipset and the one sent to me has a different chipset. In addition, they can even send you the C-U0008 but, according to them, the C-U0007, C-U0008 and C-U0010 have no specific differences It works well if it is only to use a keyboard or mouse but the product they send you is not the one announced and if you are going to update the firmware, you can be throwing money as it happened to me. I do not open a dispute with the seller based on the comment of another user (it is wasting time) and also that I do not want AliExpress to cancel my account because the seller so decides (also badly by AliExpress on that occasion).
Well, beware of this seller! The model shown on the picture is U0007, but they sent me U0010, which is TOTALLY DIFFERENT CHIPSET! Then the seller refused my dispute. This is not the way to do business and you deserve the lowest possible rating!
