After more than a decade of waiting, Amazon’s first color Kindle has stumbled out of the gate. An issue with the new display has left Colorsoft buyers leaving unfavorable reviews. At last count, the e-reader is hovering around 2.7 stars.

The company confirmed the display issues that are affecting a “small number” of units in a statement sent to TechCrunch.

“We’re aware of a small number of reports from customers who see a yellow band along the bottom of the display,” Amazon says. “We take the quality of our products seriously and are looking into it. If customers notice this on their device, they can reach out to our customer service team.”

Amazon has yet to acknowledge reports like this one from Good E-Reader stating that the company has pushed back shipping on units as it scrambles to find a software fix.
