Query: Great bounce feature, but defective.

We bought three of these, two Canon and one Nikon. The Nikon recycled much slower than the Canon. When I contacted Cameta and spoke with Rich by phone, he asked me to try it awhile longer to see if the recycle time improved, and if not they would replace it. The flash got worse, and sometimes will not turn on at all now. When I contacted Cameta again, they now say it is beyond their warranty (because they asked me to try it longer) and they will not replace it. The Canon flash is still working fine, but I would have to caution folks about the Nikon and Cameta.
