In my review of the RG300 I was mildly critical of the TFT panel that they used. For a JZ4760B handheld it was perfect in almost every way apart from the lack lustre screen. A few weeks later there was a new version released with a slightly better panel, but it wasn’t really worth the upgrade. But now there is a yet another new version available and this time it contains an IPS panel, making the RG300 the absolute best JZ4760B handheld available in my opinion.
The new improved RG300 is available from AliExpress.
