[EX Q]: This portable heater is good for use in your office, den or sleeping area..It is quiet and efficient,and is good for spot heating...please keep away from drapes or rugs,and small children,who might mistake this heater for a toy...Otherwise this is a good deal...Mine came with a remote to adjust setttings more easily...4 star rated...
[EX A]: Positive

[EX Q]: Comfortable right out of the box. Well made. Durable. Can't vouch for the waterproofing of them, as I have learned many moons ago.....no shoes are waterproof. I refuse to test them, once you do...they never seem to be the same.
[EX A]: Positive

[EX Q]: Absolutely awful.I watched this Christmas special with an effort. When I think of bad Christmas movies, it's Santa Claus (1961), Santa with Muscles, Santa Claus Conquers the Martians and A Charlie Brown Christmas.I can't believe this won an Emmy, Hollywood's most famous TV award! I would have to be on drugs in order to recognize it as such.I beggar you not to listen to the others! It's not a Christmas classic, they're lying. How can a Christmas movie have touching up on a perfectly innocent tree, teasing C.B. because of the Christmas tree, and Lucy at the end saying dialogue that I try to forget:"Charlie Brown IS a blockhead...but he gave us a nice tree."Something that Ed Wood would perpetrate, in my highly professional opinion.
[EX A]:
Negative
