I own a pair of these waders and they are okay. I bought them based on price point and fit - they were what fit the budget at the time.
I got mine in February and have fished quite a bit in both rivers and lakes (pontoon boat), fresh and salt, since then. On the last few outings, I've noticed my fleece was wet behind my left knee. I've made a couple of halfhearted attempts to locate the leak, but haven't discovered it yet. I can't help but think I may have hooked myself one day out on the boat, but it might also be a leaky seam.
Somehow, I'm not really that disappointed about the leak. I guess I knew I was buying something at an entry level price, so I expected entry level performance. I know this isn't exactly a ringing endorsement, but its also not a strict condemnation.
