Bests & Worsts Reviews from Amazon

I'm giving this 1 star for two reasons. First is the fact that they "hid" the statement about avoiding use of this product in high temp environments" in the last sentence of the description after telling you everything great about the product. But more importantly is because of the very fact that they HAVE such a restriction on their product. Tell me of any car in the summer that does not have a high temp environment during summertime months where cars get up to 120-140+ degrees internally. This renders this product virtually useless. I can't believe they bother to make it. Check other 1 star reviews that back up my claim. Regardless of what the Q&A's say, they apparently can't handle the heat.
