Been looking to get one of these sanders for a while. But sanders of this form, cost many times more, like 3M is 3X more, Festool is 4X more, and the Mirka 2X more. While these are great sander, for a DIY weekend warrior, paying that kind of money for a sander is silly. The alternative cheap versions has a lot of negative reviews. Vevor is a familiar brand, always economical while having reasonable performance for the price. The interchangeable 5" & 6" pad is icing on the cake because the other brands, you are pretty much stuck with the size you buy.
I have multiple sanders to compare this with, Dewalt ROS, both corded and cordless. Portercable square pad sander, Ridgid, and an old school Firestorm. And first thing I notice is the vibration, compare to those other ones. It is noticeably less. 20 mins in to sanding, my hand isn't numbed. Still fatigue but, didn't have those tingly numbed feeling I usually get.
I know many reviewers will mention noise as a criteria. To me it made no difference, because I am running a lot shopvac and that drowns out everything. Still need hearing protection. But what I do noticed is, it ran a lot cooler compare to my other sanders. All of them would have the same shop vac attached. While we are on the subject of shopvac, with the shopvac on, I don't see any noticeable dust particle in the air, even after 20 mins of sanding. My other sanders I would have the air filtration on already.
I recommend this to people who are using this as a dedicated work horse for day in day out sanding. I don't think it will stand up to that type of punishment. Probably better off getting those more expensive models I initially mentioned. But for people that use it on the weekend and want most of the benefits of the more expensive sanders, this one is great.
