These two units integrate seamlessly. I have not had to configure anything to get a working system that focuses better than I can achieve manually. Great to be able to refocus the OTA from the warmth of my study!
For a critical review on backlash etc. please look elsewhere. As it works out of the box with mu Esprit 100ED I am happy.

I bought this as my 1st venture into auto focusing. It looks to be a solid, well made device. I had to get creative when fitting the bracket to my focuser. The bracket has ridges on one side, this was the side that had to face up to my focuser and it was pulling off square when I tightened it down, it would be better if the bracket didnt have these ridges and was smooth on both sides. I'd have given 5 stars were it not for this. Other than this, fitting wasnt difficult and set up was easy.

Well made piece of kit. Works well. Just make sure that you can rem ove the coarse focussing knob on your telescope before you buy, (for a horrible minute I thought mine would not). Good value compared to other offerings.

I am so happy with this EAF that I bought 2. One for each telescope. The only issue I had, was that I needed to find screws that match my telescopes focusers. The screws supplied with the EAF did not fit the SkyWatcher 72ED or the Bresser Messier AR-127L. But I found some in the local store and everything works great.

Well finally committed to purchasing this ZWO EAF focuser and installed on my TS65 Quad, all fitted without any hole adjustments just one M3 longer screw to lock the bracket to the scope R&P focuser. Connected it all up and with the hand controller connected, loaded the Ascom driver and USB lead and all worked perfectly. Set the zero point limit a small distance away from the maximum "in" position of the drawtube and set the maximum "out" steps to cover my usual focus position and additional couple of 1000 steps and all behaved as expected, just needed to tick box in settings for reversed movement. Tried it out on NINA and APT on the only clearish night so far and both NINA and APT auto focus routines behaved beautifully achieving better focus than I have ever achieved manually with Bahtinov etc. Calculated the overall backlash of EAF and R&P focuser and only 35 steps so set that into both programs and it performs really really well.

Highly recommend and as usual, FLO supply was, as always, brilliant

Purchased this to fit my Skywatcher Evostar 80ED. It works seamlessly with my ZWO ASIAir Pro - can highly recommend. This is a massive improvement and glad I made the purchase. I had a few problems attaching it to the focuser, but FLO helped me out and provided prompt and first class service as always. I ended up attaching this to the left and right screw holes (next to the centre tension screw hole) using M3 15mm bolts - be careful not to put too much tension on the focus tube though. I am truly impressed with the after sales service that FLO provide.

Have attached to my William Optics ZenithStar 73. Fittings needed were included in the standard pack and were simple to apply. Hand controller worked without a hitch and temperature sensor works fine too. Will be configuring and controlling this using the excellent N.I.N.A software suite.

Got it to fit my Explore Scientific 80mm triplet. Needs longer bolts (Try M4 20mm or 25mm with washers) Massive improvement over manual focusing.

I only docked a star because none of the included screws fit my 130PDS focuser and I had to buy more. Other than that it wasn't much fuss to fit and it works a treat. I use it with APT and focusing is now a breeze.

Compatible with lots of different focusers, easy to install on the ED72 and a GSO SCT (my testing so far) with many attachment options included. extremely good fine control, tested with Nina and Ascom. So good I bought a 2nd one.
