The 'Thumbs Up' is a marvellous device, and all that has been said about it earlier is correct.
I have just bought the version with the cold shoe so my Frankenfinder can be mounted on it. That means I have a spare 'simple' model, (model 1, shorter version) for sale if you or anyone wants it. Feel free to contact me if you do.
Or I may just keep it in case I do go and buy that black paint MP sometime...
