Shows signs of it being used.
Tuesday, 22 September 2020  | 

I haven't fitted this yet only looked at it. the worse is a shinning line in the inner light baffle about 10mm long. (hope it does not cause a light flare)
the large ring which fits into the back of the telescope has some scratches on the front of the ring , no large cap which I have seen in a you tube video.
The Nylon grub screws one or two shows signs of badly use of a screw driver on them, which is puzzling as they are if anything two easy to turn with a proper fitting screwdriver.
I rotated the with just a wera long flat blade bit 6mm.
This is being sold as brand new and I would describe it as shop soiled at best. The focusing rail shows signs of use/wear.
I have already sent a Baader sky surfer V back because of red dot is damaged and signs of use. They have received but have not acknowledge.


Response:

Sorry to hear of your dissapointment. The focuser was not secondhand or shop soiled (it was supplied to you in a new unopened box and we don't have a shop) but clearly the fit and finsih is not acceptable. Please email us to arrange collection/replacement.

Regarding your other returned item, we advised you earlier this month Baader no longer have stock (Covid-19) so it will be some time before we can dispatch a replacement. We also offered a refund.

HTH

Some nice stock R&P upgrade!
Tuesday, 1 September 2020  | 

I bought this Crayford as a replacement of my Celestron C6R 150/1200mm stock R&P. The focuser has fitted in to C6R opening no problem, all three screw holes are at exact match. After final assembly I've tested full in/out collimation and it is spot on, which is a pleasant surprise in comparison to stock R&P. Even unlocked, the focuser holds a heavy Nikon D800 no problem while pointing at Polaris (tension would need to be adjusted out of the box probably) Finder shoe 2x holes are there also.
Now a bit of a negative side. My version has arrived with a seriously stuck grub screw on a single speed handle side, leaving no option to fit in a focusing motor easily. A workaround is as follows - a shaft and a single speed handle can be removed altogether by unscrewing a grub screw from a double speed side. Then a replacement 4mmx100mm stainless steel shaft to be accuired (plenty of a modelling shafts available everywhere). That allows to fit in a standard Skywatcher motor, although some drill work would be needed to fit a motor plate.
There is also a small catch with a focuser rotation - if using a heavy finder make sure to lock a focuser rotation control srew or it could rotate by itself when you don't need it
I would put an overall rating as 4 stars - very solid, but could be slightly better. Can't go wrong for the price though.

Very Smooth focuser without tilting.
Wednesday, 26 August 2020  | 

Great for My Omegon 102mm ED triplet.

After removing the flange adapter, it was attached to the telescope side.

Much smoother than the original focuser.

Great to use~!

Great Focuser!
Sunday, 9 August 2020  | 

Upgraded the stock focuser on my 100ED Evostar. Big improvement for visual use. Holds the finder much better(with a two screw bracket), and I can finally use my heaviest eyepieces (APM 100's) looking at the zenith. Did require some adjustment out of the box, but it was easy to do.

Upgrade on Starquest 102r

Significant difference between the stock focuser! This focuser is smooth and acquire focus is no more difficult.... Fits perfectly on the Skywatcher Starquest 102.

Great replacement focuser for ED80
Monday, 25 May 2020  | 

The focuser is excellent build quality with smooth action and fitted straight in to ED80 by simply removing three small screws from scope. Screw holes in this focused aligned precisely. My only gripe is that I had wanted to fit my Sesto Senso autofocuser unit in place of the knurled focused knobs but the grub screw on the microfocuser knob fits none of my Allen keys that I use on other focusers aon other scopes...seems to be somewhere between 0.5mm and 1mm.

Much better than expected
Friday, 8 May 2020  | 

Have a Sky-Watcher Evostar 120 and as have seen in comments else where the focuser could be better, often had difficulty to get a sharp focus for reasons discussed in reviews here.
after a lot of looking there may be better focusers but for the money this what could justify for the telescope.
only issue was the fitting the focuser. when removed the old one i needed to remove a little paint inisde the tube to allow the new one to fit, probably bye bye waranty .
but the difference .. its so smooth to focus now, the rotation of the focuser so that dont have to release the diagonal to reposition eyepiece (is wonderfu) and best of old the attachment of the diagonal to the focuser is solid, no movement unlike the R and P focuser that came with telescope, when i was afraid the eyepice could fall out due to the poor cpnnection on the diagonal.

is like a new telescope !!!!

Support from FLO team was quick and helpful

thank you

Replacement focuser
Wednesday, 18 March 2020  | 

I looked at the other focusers out there - Moonlight, Baader etc - and although they are premium quality units, I just couldnít justify the money for what is just a bit of a nice hobby for me. So, I bought this one to go on my Skywatcher 80ED, and quite honestly itís brilliant!!

Undo 3 screws on the old unit and remove, slot this one in, put 3 screws back in - job done literally took 5 minutes. Perfect fit and alignment with the tube.

Really smooth action - the original SW had a constant sticking spot, despite following all the Ďtuningí tutorials. The focal markings on the top mean that I can always get straight back to 99% focused, if the tube gets moved or pushed in. Then just a tweak with the fine knob.

Well worth the money to get rid of the SW unit.

A vast improvement over the standard one!
Monday, 9 March 2020  | 

Vey well made, for me, the most impressive feature which I hadnít even realised it did, was the fact that it rotates too! The standard one didnít! The benefit of this is that when your mount has rotated 180 degrees your eyepiece can be rotated back up to the vertical without having to adjust everything! Itís just one locknut to loosen. Itís worth having just for that! I canít believe this isnít made more of in its feature list! Of course the actual job of focusing is also superb.
