    It's a good USB card reader, but...
    4 Stars
    It's a good USB card reader, but...
    I bought this as a cheap USB card reader, and on that front it doesn't disappoint. It has an SD slot and a MicroSD slot...just for the heck of it I put in two cards at once, and it only read the SD card. Not that I realistically expected it to pop up with both cards on my desktop, just sayin'.It's a bit bulky for a card reader, but I'm not going to say that's a negative, since part of the benefit of this one is being able to store a card inside it, so it necessarily has to be large compared to others that load the card sticking out the side, for example. But the size might be an issue for some people, as USB ports are occasionally spaced kind of tight, so I could see situations where one might have difficulty inserting it properly.However, I got this one because it had three extra features I liked, but it fails at two of them.* Card cover - this is great. In fact exceeds expectations. You put the card in, the cover snaps shut, and because of the way the catch is designed, you can't easily pull it open just by hinging it out the same way...you have to squeeze the sides of it and pull it open. I'm making this sound more complicated than it's worth -- my point is, it's very easy to intentionally open the cover, but very difficult to accidentally open it. This will be excellent for dropping this in my pocket or bag and not worrying about losing the card.* Activity light - very faint. I could barely tell it was on. It was slightly improved when I peeled back the sticker cover and found there was some crud inside the socket that was blocking the light, so I pulled that out and replaced the sticker...better, but still pretty faint in direct light.* Rotating cover -- the bit you can rotate around to protect the USB connector -- is so loose as to be pointless. It has little points in the plastic meant to be stops, but there's not enough force to hold the cover there. It won't protect it at all in a pocket or bag, it'll just slide right off. I'm just going to remove it.Still, it works as a USB reader, so. I would've given it three stars because the other bits are kind of misleadingly useless, but given it's cheap and I will really appreciate the card cover, I'll bump it up to 4.
