I have appreciated the design and form factor of the MicroBlade Pill Ti. I have been a bit surprised at the difficulty in getting the blade sharp enough. It has been useful, but on several occasions, the blade didn't seem to be sharp enough to cut thin plastic packaging or even packing tape. I have used the MicroCarry sharpening kit, but still feel the edge is not as sharp as I'd like. I'll probably use some other sharpener to get a better edge. That said, I do really like the tool. I bought one for all six people in my family. Some of them love it, some less so.
