Product review (5 stars): Worth the money
I have just enough space for the washer and dryer in my laundry room. Once they're against the wall, I'm not getting behind them to make sure they're connected properly. Once I installed this, I just pushed the dryer back and it connected itself. The magnets are strong, so I highly doubt it will leak hot air. It might even be a better seal than the traditional crimped, taped connections.

No more crushed, barely connected dryer duct.
