The Rode smartLav + (http://amzn.to/1DSiunk) is basically a good product. Compared to its predecessor, it roars significantly less, but still clearly audible. It also strongly records votes weighted so rather dominate the middle audio frequencies. That may be enough, but for a really high quality recording that is to be criticized. Otherwise the microphone does a very good and sophisticated look as such.
I set to music by many videos on Mac, so a lavalier microphone would not absolutely necessary, but is very handy. Compared to an old large diaphragm microphone that already years as is and has a strong background noise, which is smartLav + but a joke. The Rode rushes more and the difference in the voice reproduction is enormous. But for me, a very good sound quality was very important, which is why I have decided on the desk for the Rode NT-USB (http://amzn.to/10O9IKT) that is more expensive and plays in a different league, but pure Studio quality recording.
Of course, no comparison, but who wants quality, is the lavalier basically not quite right. Especially for the road etc. is smartLav + (http://amzn.to/1DSiunk) a class microphone, and there are as mentioned above still need for improvement.
When it eventually gives a smartLav ++ which hardly rustles and takes similar to a studio microphone frequencies, or interpolated, it would be a very good solution. Therefore, there is only one star deduction.
