Review on 📸 Rocketek USB 3.0 Portable Memory Card Reader Adapter for Micro SD Card/TF Card by Danielle Nosbush

My son and I used this to copy boot files for a new Raspberry Pi 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 connected to my Mac and went to bed. The next morning, the SanDisk microSDXC disappeared from the desktop (no longer mounted in macOS Finder) and was HOT. I was concerned that the microSDXC card was dead, but after letting it cool down, I removed the microSDXC from the reader and plugged it into the Raspberry Pi. Pi booted fine. Pooh! The microSDXC card seems fine (fingers crossed it stays that way). Rocketek was apparently dismantled due to some sort of thermal shutdown. Since then, I've noticed that Rocketek ALWAYS heats up quickly with every microSDXC card I try. He's getting hotter and hotter even when he's not doing anything. With that in mind, I definitely recommend FAST COPYING YOUR FILES with this Rocketek reader and REMOVE IT IMMEDIATELY. Do not leave it connected, otherwise there is a risk of burns. Seriously, if you leave that Rocketek reader plugged in, be sure to point a desktop fan at it or it may overheat and shut down. Consider keeping a fire extinguisher nearby in case of self-ignition. :) As mentioned, removing microSDXC from a Rocketek reader can be difficult. However, there is usually a small protrusion at the end of the microSDXC that you can use to pull the tiny card out of the reader. The card seems to be easier to remove after inserting and removing it several times. If it wasn't for the nuclear hell heat issue I'd give this thing five stars because it works well and is fast. access time. Well, at least if my stove breaks down in the winter, I can heat my house by plugging in a Rocketek reader.
