Review on Optimized Concrete Anchorage: Arrow Shed AK100 by Donald Vargas

Save money it is useless. The holes don't line up, I had to redrill 90% of mine. I could not attach the cement anchors. I haven't seen a way to hammer them in and leave the threads bushing down. I was able to get one, I had to use a different sleeve to pull it over the one to take it off. It took me 5 minutes (because it was in the corner and harder to reach) so I ended up just using cement screws. Also in my kit were 3 shorter screws. He went to the masonry with a drill, but it was very difficult) cut through the cement and made no, but about 4 holes. Luckily I already had another set of decent stone bits and I went and got one. If I had to do it all over again I would just go over the sub floor with cement screws every few passes, this item was a waste of money, I wouldn't recommend it at all.
