I think it is personal preference.
I love mine and have several friends that like their's as well. I know it takes a little practice. Most of the people I have talked to that did not like it, only really tried it once or twice. You do need to practice, just a little.
Check out some of the webs sites and forums online. It gets good review and many of the forums talk about some of the problems and how to avoid them. Good luck.
