It's a worthwhile investment that delivers consistent performance and convenience over the long term.

This product works great. I bought a different one, but I didn't say it was Windows compatible, and my computer kept showings errors. So far, this one works great and downloads fast. I recommend it to anyone.

I use this regularly and it works great after a year and a half. The USB connecting wire is short but thick and sturdy. It holds up well. Sometimes the cards need to be inserted over again because they didn't read the first time. I usually blow a little air in (I use a little old school camera dust cleaner with the air pouch you squeeze so the air shoots through a small tube) just to make sure the contacts aren't dusty. I recommend storing the reader when not in use to avoid that but I sometimes get lazy and dont bother.There are two slots, one for standard sd and one for micro sd cards. I never used both at the same time so I can't say if that's possible or not.The transfer speed is pretty good if the cards are in properly and their contacts are clean. I think the time is between 13. And 17. mb per second. I dont know how that rates against others but that's the best I have personally encountered.I've experienced other card readers whose circuitry gets fouled up fairly quickly and becomes worthless but that hasn't happened yet after a year and a half. I am super careful with all card readers so not to drop them just in case of that internal damage. I don't know how delicate this one is but I assume all card readers are delicate. I once had one last less than a week once. This reader is going strong after 18 months. I suspect it will last as long as I need it.

I needed a way to copy uSD to SD cards, and this seemed like the obvious low cost answer. While it works just fine, it would have been nice to have a led activity light in it. I've caught myself several times getting ready to pull the card out before it was done copying. Not a super big deal, but again a nicety.I've been using this for some time now and so far no signs of it breaking down. Needless to say even with the slight complaint, I'm still quite happy with it.

I got this for a 2018 Tesla Model 3 to use 2 memory cards from one USB port. It works ok, but I did need to use a single card reader for the car to use the dashcam format feature. After the card was formatted and usable as a dashcam I changed it to this reader and it continued to work correctly. So this does not allow for formatting, but it does appear to work ok for daily dashcam use. It can read both cards at the same time without issue while I have a phone charger plugged into the other available USB port.

Got this today - first time using a card reader and an SD card. Instructions don't come with these but it is easy to figure out if you have some basic computer knowledge. If not, you can find help online easily enough. Driver automatically downloaded once plugged in to the PC and I went from there. It worked seamlessly and so easy transferring photos off my Nokia Lumia 1520 phone to my computer. My phone takes a MicroSD card and I like that this adapter can accomodate both a regular and Micro SD card. Worked great for the price - can't understand why anyone would pay more for a card reader - especially one that can only read one or the other. I did read reviews on this prior to purchase and noticed some people saying the Micro SD slot is a bit tight. I didn't want to take a chance using the first time and break my Micro SD card so I did get a card adapter that I could put the Micro SD into and then slid it into the regular SD card slot. Now that my important photos are off my phone and into the computer, I'll try the Micro SD slot in this later and see if mine is tight fitting as well.
