I have the same unit, and my drawers are hard to open. My wife has a real problem with some of them. The hardest ones are in the kitchen, the bedroom not so much. I know they have to be tight for travel, but a little less tight would be great. Maybe if someone has a fix, they can pass it on. If we are lucky, maybe we can come to a happy medium. Other than a few small things, I am well pleased with my 3670
