Well well well
You won't get a close shave with the oneblade. It is good if you have sensitive skin and it's quick. You'll look presentable after shaving with it but the hair will be back quickly. I recon you'd need to use daily to get the look you wanted with it.
Damn, it looks like a decent device however based off of what you said, I'll pass. I had a really great foil shaver, however it took a few passes to get smooth and the clean shave would only last for a day.
