The parts I ordered arrived in a reasonable timeframe, but there was a problem with the fit. These are complex structures with undercut channels that must fit an existing metal part precisely. Lefteri in the QA group provided superb support - to understand and verify the problem, then get the designer and production team to confirm the problem and address the solution. The support was fast and intelligent, and I was kept informed of progress at every step of the way.It's clear to me that Shapeways' goal is 100% customer satisfaction, so I will be a returning customer.
