I'm sorry to hear you're having problems, but there was a firmware update released in September. Please try updating to this firmware to resolve any freezing issues.
Regarding the quality, the components of the R1 are not as high a quality of our flagship DJM line in order to keep costs lower, this is a common design/construction technique in every industry. If you want the luxury and performance of a DJM, you can't expect to get it in the cost of an R1.
I will thank you to watch your language in future posts.
