Customer Reviews

Solid Product!The card reader has been working well up until now, and I haven t had any problems using it (After 5 months at the time I wrote this review). Its size it is really good to be carried everywhere. It is a little bigger than a quarter. Although, if you wonder about carrying it on a keychain the answer is no. There is no hole or a key ring to put it on your keychain. I didn t really care about this as I thought of disassembling it to use in a project that I planned on getting to someday. So keep that in mind if you were looking for some kind of pen-drive keychain.The material from which this product was made out of doesn t feel sloppy as other SD readers I have seen out there. Further to my previous comment about disassembling it, I found that it is difficult to do so because all is really closed made of an only solid plastic case. It is not made of two parts that just pop up to be opened. So although I wasn t expecting to be that way, this is a positive point just because it s shown to be a good product after all.I like the fact that instead of putting the micro SD card on the back, it goes into the usb tip. I also have to mention that there isn t any cap to cover the tip, which it can be a disadvantage. The SD card fits kind of tight inside the slot, so it is very improbable that it will fall down due to the lack of a cap. Yet, you still have to be careful and keep an eye on it if you re on your way down to somewhere and as the saying goes better safe than sorry .5Awfully FastThis adapter is one of, if not the fastest I've found. Although I have not done any testing of this, it may even be faster than all of my usb 3.0 thumb drives I have, which is surprising.It has an aluminum housing which may be a necessity to reliability/performance, as it gets really hot when you are copying files to it for any length of time, i.e. it may be as much a heat sink as well as a durable cover..I just now copied 5gig to it, and you know how some cards or thumb drives jump up really fast at first then slow to a crawl, this does none of that. It started at 20MB/sec, quickly jumped up to 25 and stayed between 25 and 30MB/sec until it finished.Although not a fault of the product since I purchased it knowing this: I wish it had a cap or cover, and even a carry ring for a key chain would be helpful.Regardless, it is awfully fast..5Works with large cards and protects the cards in a tablet from being bumped and brokenOne thing I dislike about many other card readers for USB is that when you use them, the micro SD extends outside the rest of the unit. You just need to bump it once the wrong way for that edge of your micro SD card to snap off and then your card (and data) is gone. So this one puts the card inside the USB connector and while mine hasn't gotten too warm from using it, it seems to be working OK with casual use of the micro SD card. For me, just having the micro SD card shielded from an accidental bump is the reason I got this one and it seems to do the job.My Dell Venue Pro 5056 has a bad micro SD card slot inside so a USB reader is my only option. For me, this worked with my Sandisk 200GB card formatted with NTFS and I haven't had any problems yet.4Rocketek Burns H.O.T.Background: I operate a 2017 Mac Air and chose this over the newer Macbook Pro line due to USB availability. I also enjoy using Micro SD (MSD) cards as a poor man's partion drive system and so I hve files compartmentalized by MSDs. I carry around my cards in a very convenient "DimeCard Micro 8" carrier which is the size of a credit card. My SD slot has a 256GB MSD which doubles the memory on my Mac Air.The Review: I have a USB 2.0 MSD to USB that is the size of a wireless mouse dongle so its pretty small but its 2.0 tech so I thought that I would upgrade to 3.0. After searching for something as small as my previous adapter without success, I decided on the "Rocketek 3.0" for its relative size and cost. It protrudes from the USB port a little more than one half inch, more than double my 2.0 adpater. With the 2.0 I could leave it in and not worry about snag but with the newer Rocketek, I would have to remove it before travel. This was acceptable to me as I have my MSD carrier and it would be used as required. So form, function, etc... all good but there is one major flaw and concern.This little drive gets hot, hot, HOT to the touch. I have fairly heat resistant fingers but if I hold onto this device with my thumb and index finger... I can't hold onto it while plugged in. You will literally remove your fingers and rub them together, its that hot. The concern here is obvious. I don't know if this will damage my MSD or cause other problems down the road. You might say not to leave it in for long periods of time but it gets that hot near instantly.Due to this concern, I don't plan on using this device at all unless under dire circumstances... as my back up to the back up. So beware of this issue before you buy. You may be more risk tolerant than me but my data is little bytes of family to me and one of my most critical resources. Of course everything I have is backed up but that isn't the point. The point is that using this device doesn't necessarily solve my accesibility problem, it instead creates a liability.Just wanted to share my thoughts and opinions. I hope it helps.3Just not very goodIt works well.It gets quite hot. The heat has caused me issues a few times.If you are going to be transferring large files frequently, get something else. This will overheat on you.UPDATE(12/5/2018): The overheating is strange and annoying but this product has trouble connecting to your pc. Let me elaborate, you plug it in and sometimes your computer doesn't detect it. You have to wiggle it around hoping it will get properly detected. Total waste of money, I'd expect this kind of bs from a $1 item direct from china but not for the $9 paid.1Works fine for quick copies, but eventually BURNS WITH THE HEAT OF A MILLION SUNSMy son and I used this to copy the boot files for a new Raspberry Pi over to a brand new SanDisk 64GB Extreme microSDXC card using my MacBook Pro. After copying the files I left the microSDXC in the Rocketek reader plugged into my Mac, and went to bed.The next morning the SanDisk microSDXC had disappeared from the Desktop (no longer mounted in the macOS Finder) and it was SCALDING HOT. I was worried that the microSDXC card was dead, but after letting it cool off I removed the microSDXC from the reader and put it into the Raspberry Pi. The Pi booted fine... whew! The microSDXC card appears to be okay (fingers crossed it stays that way). The Rocketek had been apparently unmounted due to some sort of thermal shutdown.Since then, I've noticed the Rocketek ALWAYS heats up quickly with any microSDXC card I try. It just gets hotter and hotter even if it's not doing anything.With that in mind, I would definitely recommend QUICKLY COPY YOUR FILES with this Rocketek reader, then IMMEDIATELY DISCONNECT IT. Don't leave it connected or it will become a burn risk. Seriously, if you leave this Rocketek reader attached, you should aim a desk fan at it, or it may overheat and unmount. Maybe keep a fire extinguisher nearby in case it spontaneously combusts. :)As others have mentioned, it can be difficult to remove the microSDXC from the Rocketek reader. However, there's usually a little ridge on the end of the microSDXC that you can use to pull the tiny card out from the reader. It seems like it gets easier to remove the card after it's been inserted and removed a couple of times.If it wasn't for the nuclear hellfire heating issue, I'd give this thing five stars, because it works well and has nice fast access times. Oh well, at least if my furnace breaks down this winter I'll be able to heat my house by plugging in the Rocketek reader.3Very nice compact reader at true USB 3.0 speed.Very compact, probably the most compact true USB 3.0 microsd card reader I could find anywhere. with a Samsung EVO 64GB card, reads 90MB/s and writes 60MB/s, limited by the speed of the card itself. definitely a true USB 3.0 speed. The micro-usb slot built into USB connector is very tight and secure, no need to worry about losing the card.5Hot Enough to BurnI use this adapter with a MicroSD for Tesla's DashCam and Sentry modes. Today I was transferring files to my laptop for review and the adapter got so hot it burned my fingers and I was unable to remove it from my laptop for ~30 minutes. I'm highly concerned about an external device getting this hot. It will eventually destroy the MicroSD, and it also raises concerns of safety, especially when the device is sitting in a hot car that is writing video to it continuously.I absolutely DO NOT recommend this product.1Fast reading, gets full read speed on Sandisk Ultra cards and full A1 speedThis reader has a few shortcomings (it gets hot and it is a bit picky with some cards) but it's the fastest reader I have ever tried. Tested with a 32GB A1-rated Sandisk Ultra card and got over 94MB/Sec sequential read speed and over 2,000 IOPS.EDIT: Upon further testing I found my 32GB Sandisk Extreme PLUS card (pre-A1) to perform even better, with over 85MB/Sec sequential write speed and still exceeding A1 IOPS despite the card not being stamped A1.Definitely a reader to consider for the performance-minded.Keep in mind that as another reviewer mentioned it can be a little hard to pull the card out.4Fastest reader I've found, I carry it everywhereThis reader isn't perfect, but it is really fast.Pros:* Actual USB 3.0 (I have a dozen readers that turned out to be 2.0)* Fastest reader I've found (with the right media)* Affordable!Cons:* Gets hilariously hot* Sometimes the media is difficult to remove, but I have always managed.There are a few negative reviews for this product, but they are the minority. It is awfully inexpensive so I guess there could be quality issues for some, but I own 4 now and have had zero problems. Since the quality of microSD memory modules varies greatly (see my reviews) I think that is probably the culprit. I recommend a fast module like the Samsung Pro Plus or SanDisk Extreme. My photo shows a copy in progress at 90MB/sec from a Samsung Pro Plus.The heat is really something, probably because the reader is so small there is just nowhere for the heat to go. I'm not worried about the electronics, which are safe to about 185 degrees F (85C). But it can get almost too hot to touch, and I plan to add a couple heatsinks to get this under control. There are inexpensive adhesive heatsinks designed for the Raspberry Pi here on Amazon that would work. I will use one on each side of the grip.Of course, you can always use a cloth or just wait a few minutes for it to cool down.5
