Review on 📱 CY Mini USB 3.0 to Micro SD Card Reader + Micro USB 5pin OTG Adapter for Tablet/Cell Phone - OTG100set by Corey Krull

These items are amazing! I've tried them in various flash drives and card readers and the only one I've found that won't fit is the Lexar Twist Turn (too tight in TT but they fit a different style of Lexar). Works fine with my Samsung Galaxy Note 4 with OEM Kitkat 4.4.4, my rooted Hisense Sero 7 Pro tablet with AOSP 4.4.4 Kitkat and my Nvidia Shield tablet with OEM Marshmallow 6.0. Ordered on April 2nd and received on the 15th. Not bad for shipping from China. EDIT (2016-06-23): They are also great for use with a Raspberry Pi Zero! Use with USB WiFi dongles, wireless keyboard dongles, or to connect a USB hub. I use one of those $4 USB WiFi dongles for pcDuino/Raspberry Pi and it works great. The fit was a little tight, I had to use pliers to pull it out the first few times, but after a few insertion/removal cycles it loosened up. On the other hand, both the OTG adapter and the USB Wi-Fi dongle are inexpensive enough to simply set aside for your Zero. If you edit the /etc/wpa_supplicant/wpa_supplicant.conf file on the microSD card to add your wireless SSID and encryption key, Zero can boot completely headless and automatically connect to your network, and then you can use SSH to unlock it manage. I also used them to connect a 4-port USB hub (OTG to USB cable adapter from hub). I used two hub connectors for the WiFi adapter and a micro USB cable to power the Pi-Zero from the hub itself. This left two more USB ports available, and I only used one outlet to power the hub and computer. new USB-C versions of these handy little adapters and they work great. They don't go as deep into the plug as the micro version, but I don't see that as a problem. As mentioned above, they only support USB 2.0, but keyboard or mouse buttons are fine.
