Maybe it is just a string of bad luck, or maybe it IS exactly what I think it is..stuff just ain't made the way it used to be. From the muffler on my car, to my dog's flea collar, to a simple little glue stick to make a minor household repair...NONE OF THESE THINGS DO WHAT THEY SAY THEY WILL..AND WORK!! "New and Improved" my butt!! Now, before you say, "buy better quality", each of the items I mentioned here are considered to be some of the best in their respective brands. I just think, it is what it is...alot of times you DON'T get what you pay for!! Whew, there, now I feel better!! Thanks!
