Technically, we can blame the name compatibility with some SLRs (Our material!), And the gateway to a PC via Bluetooth only (even with a USB cable, it is not recognized as a peripheral, big gap!).
Otherwise, the print quality is a curious ... from the viewpoint of colorimetry.
The charger is as big as the product.
Printing relatively fast and very quiet.
Overall, a very good product, in line with our expectations.
