Opinions on GR accessories - GH-3 (hood) & GW-3 (21mm lens converter)?

Hi All, I'm looking for opinions on these (I understand I need the hood adapter for the lens converter - I can't see me using it as a hood itself). I'm looking mostly for info on how well it works when shooting - I appreciate there will be some compromise on IQ/distortions, is there a menu setting you need to set?

Any pointers as to where I can them would also help (the lens seems to be in stock at some dealers but the hoods appear to be harder to find.

Regards,

John.

In terms of quality of results it all works very well, but I do think it's very clunky and inconvenient in design. The GR on its own is a very nice bit of kit, but add the rest and it's cumbersome.

John has pretty much summed it up - IMO the results are surprisingly good but it is a rather cumbersome set-up. There is a menu setting to tell the camera that you are using the GW-3 (it alters the effective focal length in the EXIF data I believe), I've forgotten to set it several times

There are a few taken with the GW-3 in this Flickr Album from 2016:
