Polaroid went out of business over a decade ago. The name is now available for use by anyone willing to pay for it. Presumably there have been some decent devices wearing that name but the two that I bought were junk. One was a Polaroid tablet and it was so poor I gave it away after about a week. The store wouldn't take it back. The poor guy I gave it to tried to give it back to me but I wouldn't take it back either.
The other was an MP3 player quite a few years ago. It worked for 2 days. It was cheaper than the postage to return it so I threw it away.
