I rated these 5 star because that is how they compare to my single channel 8' tubes. I did not order the cheaper 5 pack since some reviews said they were thin and improperly sealed. I don't know if these are thicker than the cheaper dual tubes, but I do know they are thicker than what I had.
Some of my single tubes got pinhole leaks, plus several tubes ripped around the fill hole when I tried to get them open to empty them last spring. The dual channel has twice the caps to open and close, but there are 3 great advantages.
1. They fill quicker because there is a seam in the center.
2. They don't roll like single tubes.
3. If one tube gets a leak, I need not throw it out, albeit I may need 2 units to create a "double" tube. Plus, I'll still have one channel holding down the cover instead of an empty tube.
I am placing another order now, since I only got 5 the first time. I want spares and eventually replace all my single tubes.
Negative - Very hard to open. Step on the ring of vinyl and pulled up cap with pliers. Could be due to 1st use. Will see at the end of winter.
