I bought this primarily to automate my new portable setup comprising a StellaMira 80mm ED 'scope, ZWO ASi 120 MM guide camera and ASi 585 MC main camera - all ordered from FLO after much discussion with Alex and delivered super fast and super safe, thanks.
How to fit this EAF isn't listed on the ZWO support website which almost stopped me buying it. Some simple guidance from Alex, who pointed out that the StellaMira I have is similar to one of the Williams Optics models, meant that it was a quick and easy job to fit the bracket although I did use a couple of files and here is how:
1 - I undid the outer grub screw under the focuser's coarse knob to expose an inner screw on the adjuster wheel that is accessible through that hole.
2 - I then pulled the coarse adjuster out without too much of a problem and was able to fit the smallest diameter flexible coupling onto the bare shaft before locking it down through the hole mentioned in 1 above with the smallest of the supplied hex wrenches.
3 - The bottom of my focuser includes a tension adjuster / lock knob which gets in the way of the bracket so I used a half-round file to remove some of the bracket until it nestled snugly against the tension / lock knob. When the EAF is fitted, this tensioner is not required as the EAF acts as a brake.
4 - There is an M4 screw hole very near to this knob and I aligned the central slot of the bracket with this hole and the smaller M3 hole that accesses the coupling in #1. That results in the bracket lying along the same axis as the adjuster axle. The central slot is too narrow to take an M4 screw so I eased that open with a flat needle file until the M4 screw could be fitted through it.
5 - I secured the bracket using an M4 socket head cap screw supplied in the kit in the middle screw hole and an M3 x 12mm screw and washer from my box of bits.
6 - I adjusted the perpendicular (motor) mount plate to shorten its offset and bring down the holes that align with the EAF motor using the supplied smaller hex wrench.
7 - I then secured the EAF to the bracket after inserting the shaft into the coupling and finally tightened the outer (exposed) flexible coupling grub screw onto the EAF's shaft.
Job done!
The EAF doesn't need a manual control pad if you're using it with the ASiStudio software, which I have on my iPad for use in the field.
Next thing for me will be to add a second bracket so I can swap the EAF onto my SkyWatcher Explorer 150P-DS if necessary - roll on some decent seeing opportunities.

I bought this recently along with the Tak bracket for my Espirit 100 and it was delivered promptly by Flo as usual. I watched loads of videos on how to install the product and thought it would be a straight forward process. However, when installing I noticed that the spindles (none of them fit properly) would bind my focusser at certain points. I was frustrated for most of the day and by that evening I had given up and was thinking of returning the item.
The next day I thought, let me try installing it on my other scope (WO Z61). This took all of 10 minutes to do and it worked perfectly straight away. My first imaging run with the focusser installed was seamless and the auto focus routine was bang on, so I'm highly impressed.
I'd offer a word of caution if you're thinking of getting this for an espirit 100ed. Maybe I was doing something wrong with the installation but I got a Pegasus focuscube v3 a couple of days later and installed that on the espirit without a hitch within minutes.
Overall, if you're sure this will fit your scope I'd highly recommend it!

Arrived next day as usual perfect service from flo and well packed, Can’t wait to use it when finally the sky's clear. Motor seems well made and if good quality all parts seem well made and was very easy to fit to my new scope. Will definitely be adding more to my other scopes for imaging. Plugged straight into asi airrecognises it and manually moved it in and out to test the movement and was perfectly smooth.

Very impressive so easy to use and accurate focus I left the default settings seems to work ok Simple fitting to my William Zenithstar 73 111 APO no additional parts needed

This is the second EAF I’ve had and both provide great service for automated focussing for remote use. Thanks to FLO for great service as usual.

This is a well made focuser that is controlled by the ASI AIR software or optional hand controller. Attaching it to the bracket is a little fiddly but sturdy when all bolted down.
Need to keep the existing focuser bronze coloured ring in place to stop the internals from falling out if pulled!

Purchased this back in July to fit onto my Starfield 102 and it was easy to install.
Unfortunately after installing the EAF I found it to be faulty (the motor didn't operate), so after contacting FLO and running a few tests, they agreed to send out a replacement which worked first time, and has ever since. This unit makes focusing an absolute breeze, so easy to use and ensures you can remain in focus without ever stepping outside; I control it from indoors using NINA on a laptop. Top service from FLO as always, and only knocked off a star for the initial faulty unit (not FLO's fault).

Excellent service again from FLO. Order was placed at 2pm arrived next day at 2pm. Packaged extremely well also. This is my second EAF which is to be used on my SW 130pds also purched from FLO last year. The EAF is a must needed tool and just couldn't resist buying the additional one. Keep up the great service all at FLO.

Had considered buying an EAF to compliment my ASI Air Pro & ASI 585mc camera but was hesitant to take the plunge and each time I convinced myself to get one it went out of stock. Finally bought it and fitted it to my 130pds Newtonian which was a very easy task with supplied brackets & adapters. I did a rough focus on a distant object in the daylight using the manual arrow controls. Almost 4 weeks of cloudy nights delayed my first light with it but the autofocus calibration routine ran flawlessly & my first v-curve appeared. So simple to use and nice tight round stars are very easy to achieve. Will definitely be getting another one for my refractor. As most of the reviews state I don’t know how I managed without it !!!. 5 star service as ever from the people at FLO.

Just need to try it out cannot belive how quiet it is
Brilliant prod recomend
