If you are just beginning with recording audio for films, this may be your go-to product. Its length of 3 meters is very likely to be more than enough for amateurs and small audio crews.
The big advantage of this boom pole is its price. Since it's not even 20 euros, you save so much money you can spend on a decent shock mount - which is actually required here, since isolation from unwanted vibrations and handling noise is quite bad. However, good shock mount reduces these problems to absolute minimum.
There is some slack between segments, which makes the boom a little bit unstable when its full length is used.
Before making a purchase, you should clarify your needs. If you're a beginner with filmmaking and ENG, go for it. If you've got some experience with such work already, you may be slightly disappointed with it.
