I am a 60-year-old, fat grandma...but I have a thing for fixer uppers. I just bought a house with the horrible popcorn ceilings, so I have been scraping and scraping and scraping. I was dreading the skim coat because whenever I have attempted anything with drywall in the past, it always ends up being a horrible mess.I was not confident in my drywalling skills, to say the least.I watched some videos about this thing. I asked a couple of friends who are contractors, they had never heard of a skimming blade. I was a bit skeptical, but what do I have to lose, right? I know if I touch mud, it will end up a huge mess, so I may as well try this "miracle worker".I was not disappointed! This thing makes skim coating a breeze. I used a paint roller to put the mud on. I found if I used a knife to apply the mud, I ended up flinging it all over. I rolled the mud on, then used a knife to apply to the edges. I then ran this blade across it and I swear it created a perfect finish! I was literally astounded! I finished one room today and I have a lot to go. I am now confident that I can finish my ceilings myself because of this amazing tool.I actually have nothing bad to say about it. I got the 16". I am 5'2" and this worked just fine. I think a longer length would have become to cumbersome for my short arms. I do not see a need to buy an entire kit of different sizes. I just don't see how all those sizes would be worth the extra money.I have not tried it on a pole. I think I would need more practice before that. I just climbed up and down the ladder, working my way around the room.This is a completely AWESOME tool! Buy one! You will not regret it!
