I have used my bags for about 2 seasons now with no issues, but I did have to go back and correct an installation error (my fault). When you drill holes in the plastic caps to run the air lines, make sure they are a large enough diameter to allow some movement. I initially drilled the holes to be a very tight fit with the air lines, since I did not want to allow moisture/dirt to get in. The lines ended up kinking and leaking between the bag and the plastic cap. I removed the lines and drilled the holes a bit larger so that the lines could slide freely. No issues since.
