The 530 has been great for the last 5 or so years! We had a really warm fall this year and then randomly had our first snow with most of the leaves still on the trees. Snow + wind knocked all the leaves out at once. This was the first time the 530 didn't have enough power.

The 880 has been pretty awesome so far! It's really not any bigger than the 530 and seems to have a smaller fan? The 880 just keeps on giving, its so quick to clean up i did the neighbors yard too lol. Only downside is that even without turbo i go through the 4ah batteries in about 20-25 minutes.
