2 and 4 definitely hits differently than the others 🙌

[greensun]

Very nice and interesting projects! All of them do a great job, but the last one won because it's obvioursly the most powerful. But when it comes to the costs, it's most likely the first one.

The third fan violated Dr Wheeler's electric fan invention 😭☠️
