This Costech 7 in 1 Micro USB OTG adapter/hub card reader works well. I have been able to use it with a bunch of my USB compatible devices such as cell phones, computers, cameras, and tablets with them performing well. I have a Samsung Note 5, Tab S, Asus Laptop, HP Desktop, and HP Wireless Printer and I could connect this USB cube which is what I’m going to call it, lol and could read each different memory card I put in it. I was also able to attach a mouse, and keyboard for my tablet, and phone while transferring photos from the micro-card.
It has 3 2.0 USB ports, and 4 card reader slots for SD Micro/TF, SDHC, MS, M2, and an attached power supply cord for when you add power hungry devices like a mouse and keyboard. Now I would think that this device would enable me to charge whatever external media devices I’m connected too, because of the power supply cord attached but it doesn’t. Well it does in a sense it wouldn’t charge my Tab S or Note 5, but it charged both my Bluetooth headsets so that was a plus… But overall it works as described I can’t complain about that. Especially for the price, and what it does you can’t beat it.
♦ It’s compact, portable and rectangular shaped.
