This is probably my 5th Sunbeam electric blanket in 20 years. They last and last but unfortunately after 10 years of use this new one stopped heating. Will return or replace. We will see. Hopefully they do better than previous units because we really loved it. Unfortunately it's not available anymore.

Ex Output:
Bad review


Ex Input:
I had no idea who this author was and while the story isn't bad as fantasy goes, for me none of the characters are very likable or well-developed. The one character is actually quite nice, but her backstory at start of plot doesn't make sense to me. If she came off a bit too trusting than maybe something else would have surprised me, like what happened after they left Earth.

Ex Output:

Good Review
