The device was simple to put into operation, but one could forget the manual (only images and the English text is limited to safety and product instructions). The slide switch on the radio transmitter can be easily moved and can be seen, at first glance, hardly the proper position. There is no there a (white) mark on the slide switch. Given the lack of operating instructions and missing marking a point deduction. Note: The shutter release button works with a Panasonic Lumix DMC FZ-150th Otherwise, I am happy with the product. Delivery and description to my expectations.
