I for a week.
The DIFFERENT recordings I've made are good parts (strong group sound level, guitar + bass, acoustic guitar + voice, voices speaking in an office) are excellent and invoices to wav mp3. Easy to use, intuitive trs, buttons too small ... but the battery compartment door is a horror. There are countries that are ingnieurs to invent things like a! ? ! They receive a percentage of the service or what? One false move, you force too much and I'm sure a case. Bcp functioning as too cheap! Overall I do not find that the construction of R09 exudes solidity.
The ratio quality price is good if one takes into account the sound, through the construction. Accessories sold on the other hand are too expensive.
I do it again if that choice does nothing more solid on the market equivalent quality.
