No set up required and can be left in place. Worth the money...

First class service from Flo yet again, product was in my hands two days after ordering. A bit pricey considering that it is plastic.

Haven't had a chance to use yet, waiting for the autofocuser to come into stock.
Once again delivery was very quick, so that deserves 5 star

Hand controller for EAF works as it should, would have given 5 stars but for the fact that it’s a cheap plastic case, with no protection if dropped, which given the price I would have expected a little more. FLO service and delivery up to the usual high standards.

Simple and reasonably well made. Provides a usefull ability to focus manually without using software so well worth having.

You need this if you have a mobile setup for initial focus
