Almost 2/3 of my first purchases have flown away rendering them useless for their purposes. So I have some expensive ziplock bags. I bet you know I recycle. The second purchase was a marked improvement. Most of them work well and it looks like the manufacturer made some adjustments so the valves are always centered. In the first game, my wife and I played "Where's the vent?" It minimized the frustration of finding that damn exit. I've had a silica gel backed sachet for a little over eight months. It never leaked and the dryer stayed dry. After removing the air I use a piece of packing to cover the vent because that seems to be the weakest link.
