Title: breaks in a few months
Product review: I have tried these twice already (because the store replaced the first for free). Firstly, the threads for the connection wear out really quickly (leaving you wondering why there is black dust in the unit), and the plastic connector also breaks easily. I've had two of these already and they both broke within a year. Don't bother (unless you just want to use it 2 or 3 times and then throw it away, as in that case, it works great).
Would you say this review depicts the product in a flattering or unflattering light?
