The focuser seemed to be well-constructed, but I ended up sending it back. The reason is that I didn't come up with a good way to attach it to my scope tube. It's intended to be threaded onto a tube. I couldn't find an adapter with M78x1mm threads, so I couldn't readily use it. If you're building a telescope and can put M78x1mm female threads in the tube, this focuser may be right for you.

Bought it thinking it would fit on the Skywatcher 150p classic dobsonian, but it's just a bit too wide. Much better than the focuser I have right now though, so I'm still going to try to get it to work

It fit my telescope like a glove.

Great quality but the main focuser assembly is held on to the curved baseplate with only two small set screws. Therefore the focuser moves, rocks, about the set screws! The designer forgot to put in additional set screws to keep it from moving! I was in a hurry so I removed the baseplate and applied epoxy between it and the focuser housing. It works great now. The design needs modification.

Good quality single stage focuser for the money, works very smoothly. Got here from China surprisingly fast, much quicker than stated. A+ vendor imho.
