This replaced a defective A3BLK. The folks at Avalon were so helpful and got our new machine to us more quickly than I had hoped for. Works beautifully!
Initially we were very pleased with the product, however after a few days, it started to rattle when dispensing water and a few seconds afterward. We checked the level, which is fine. The rattling appears to come from inside the cooler, and we have no idea how to stop it, or if this is a defect in the cooler
