Re: Which hookah?
I really don't think that would be a problem. I have 3 KM's all are in good shape, you just have to be careful with the KM Chillers. Sometimes they have bad welds which let water drip inside the stem, but I guess I'm one of the lucky ones and don't have any bad welds. There will be visible weld marks and such throughout the exterior of the hookah, which are fairly hard to notice. They are hand made and aren't always perfect, so you will see minor imperfections on the exterior. Nothing that will affect how it smokes.
