I have my mirka for over 2 years now. It works great. I had zero problems with it so far. I did replace the interface pad twice and the extension cord. Cost was $120 canadian for the pad and cord. The cord I replaced at the 2 year mark. I use the mirka often. It's an amazing sander. Best I've used as a professional drywall taper. The abrasives from mirka seem pricy but they do last a long time. Amazon sells a different brand, cheaper by 45%, but don't last as long. Still good though. More on reddit.com

Yeah any vac as long as you can make the connections work... Wallpro have an orbital option too and it's heaps cheaper. https://wallboardtools.com.au/volito-brushless-4mm-orbital-sander-wallpro More on reddit.com

I own two. Love them. Some thoughts— the Deros is not a pneumatic sander, it’s just kinda in the shape of a pneumatic sander like the the mirka ROS. I just want to be sure we’re on the same page because I have different thoughts on pneumatic sanders. That “pneumatic style” form factor fits really well in my hand and I love it. Other people seem to really hate it because you can knock over the sander and activate it accidentally. I use my 5 inch pad for all wood sanding applications. The six inch pad I have I only use for feathering out drywall mud repairs (I’m a carpenter who does a fair bit of remodeling). The deros is not a “material removing” sander that you can press into service to do things that ought to be done on a planer or jointer. If you want one machine to do it all maybe look at a rotex. needed accessories— “pad savers” which I believe is the same as the interface pad. High quality sand paper, I prefer 3m cubitron II (the original, not the open weave chevron cubitron xtract, but that’s because the xtract can’t really be pressed into hand sanding applications as easily). And lastly a hepa filter equipped dust extractor— absolutely essential. If you don’t have one and can’t afford one, you can’t afford a premium sander, sorry :( Random thoughts— my first one I bought used and it worked until I lost a conductor prong from the cord. “No problem” I thought, “ I’ll just clip the damaged plug end and rewire a replacement”… It never worked, despite outwardly being a totally normal looking set of braided conductors. Good news is that replacement cords are only like 20 USD from mirka. I ended up buying the second DEROS because I was convinced my first one was dead… until the new sander’s cord made the original work. The replacement came from Amazon and I have no complaints about that. I would have liked to try a festool ETS150 because there are better options for pads, but at the time festool availability was very limited. If you want I’ll trade you your old festool for my old mirka straight up. 😂 More on reddit.com
