The never solved the battery issue and the firmware support is bad. I think they will never make a new firmware for QPR1. It sounds good - but with this bad support i will definitely never buy their products again. Also the design of QP2R is based on the QP1R - there is no innovation behind - this is similar comparable to ibasso with DX50 and the successor DX90. But this should never happen in this price segment. I assume that QP2R will not continue the success of QP1R. The competition on the market is very strong.
