Well, this was a perfect ending to a long busy day. I ordered the movie under the Tucson Sun to sit back and relax. It was very very enjoyable. I'm saying all this in a long-winded way because this review requires I write 20 words. This is actually kind of a pain because I am turned off about writing anything about these. But it was a fine purchase.

Ex Output:
Positive

I bought two sets of these. They're priced at $9.50. But, when they arrived, the price tag still stuck on the item says $2.99. Nice way to hide your "shippign cost" ($6.51) from your customers! This company goes on my "Never Again" list!

Negative

I had used this product at the urging of the pet store clerk. He claimed he had over 20 ferrets and at one time had a flea problem. I vacuumed, sent the dog to the groomers for a flea dip, then came home and sprayed the entire house. I returned after a few hours, opened the widows and started up the air conditioners and picked up the dog. The next day I noticed several adult fleas, though they were sluggish. I thought..great! Then the family started getting bites and seeing small and adult fleas. I feel I wasted my money for a product that seemed to give us 24hrs of relief. Forget the claim that it keeps on acting for up to 7 mos. I am not infested with fleas, but we still have them.....and they are alive and well.
