Downloading this software on a Macbook air was completely smooth. My experience was not quite as speedy as another reviewer, but start to finish was about 35 minutes. Since internet speeds do vary by time of day and general traffic, it is helpful if you choose a time when the servers aren't at peak. Even so, I have Comcast which is never reliable or very fast, so I'm generally pleased that it was this quick.

In my climate, fleas are a real problem, and this year has been especially horrible. We have both dogs and cats, and since cats are sensitive to certain chemical pesticide carpet sprays (especially Permethrin, as I recall) we have used only Fleabusters powder in the cat areas. The main downside is that it's a bit dusty when you first sweep it into your carpeting and for a day or two thereafter. However, you soon forget it's there, and over time it seems to do its part in a flea control program that includes treating both the pets and their living space. I give it 5 stars because it works reasonably well and boric acid is a pretty benign chemical. I have not found other sources of boric acid that are as finely ground and remain mostly clump-free, so keep coming back to FleaBusters do-it-yourself powder.
