Bests & Worsts Reviews from Amazon

I am surprised by how bad this product is given the overall decent quality of Amazon products. The screen is unresponsive and freezes. Kindle books I purchased are inaccessible from this device no matter what I do to open them even though they show up on the kindle app. I cannot delete apps that I don’t want even though I am supposed to be able to do so. Too many ads show up and there doesn’t appear to be a reliable way to avoid them.
