I can find some articles on how to use them but I can't seem to find anywhere peoples impression of them using them in real projects. I have been trying to figure out how to use them and Ive had alot of problems..

Can someone out there who uses these tools on the job give me thier impression? Are there better alternate tools available? Using these really just a waste of time ?

With Coded UI Tests I see how they are good for basic javascript checking but its so basic of a example I don't think it is worth it. With web tests I like how they work but when I activate code coverage/ASP.NET profiling it doesnt work half the time.
