I had problem with the 2 screen protectors, any of them paste well on the screen. Very disappointing because I also bought the complete screen protection and I hope not happening the same thing...

negative

After just a few months of night time charging, the Apple watch won't charge. Maybe if the seller sends me a new one for free I'll write a better review.

I've been using the same USB 2.0 SD Card reader (not micro, full SD) for nearly a decade now and decided it was time to switch. I fly FPV and transferring video to my phone for review is tedious with a slow connection. This fixed that. Fast transfers, pretty well built (I like the cap), and can read a microsd in addition to a full sized SD card. I think that, in time, the grip on the cards will loosen...it seems to have slightly already (maybe 50-60 insertions/removals). Still, the little click when you lock your card in is very assuring .Personally, I would like to see the SD card spring loaded and/or under a cap so keeping it in the pocket wouldn't be a concern. As it is, the ports are exposed and likely to attract lint and other pocket debris. Still, great reader, especially for the price and worthy of 5 stars.

Ex Output:
positive
