I found this really easy to use. Got good, clean straight lines. I can understand the people having trouble holding it because it is a bit awkward until you get the hang of it. Overall a good product.
I have patchy cheeks and needed to EVENLY drop my cheek line, which creates the appearance of fullness. I've tried this many times on my own and failed at every attempt. I finally gave up and went to a barber to achieve my desired look. I don't always have time to schedule appointments to stay clean cut though. I wanted to take care of my beard grooming on my own. That's exactly what this product allows me to do. I can achieve those perfect clean lines without visiting the barber. Excellent product. Very pleased with my purchase. Love it
