I can only find here users giving testimony of good and reliable usb sticks. How come? Already three usb sticks died on me within 12 months. I bought pro license with hope for good and reliable product. Now my server is down and I lost my configuration because usb is totally not readable anymore. I totally agree with first post that there shall be a method for easy key backup/temporary key. Or better, finally, limetech should allow use of ssd drives. They want to limit me to one UID, fine. But at least it would last longer than 3-4 months.
