That is me. The do work good however, I wish I had some more amps because I am running three usb radios and charging and tethering a cell for inet. I also wish the supported pass through so I can use and charge at same time. Still quite pleased!
I use the disks in Kali to make image backups and restore. It uses a GUI so it is very easy. I mad a master image and cloned it to 4 Pis. Many times the disk gets corrupted and using fsck on the disk has always fixed it.
