Rockwell RK4245K Vibrafree 5-Inch Random Orbit Sander Review

I really wanted to love this sander.Having owned an older model Dewalt sander that was good until the sanding pad would no longer slowly spin, but would just take off and spin madly, I decided it was time to try something new.I noticed Rockwell had been putting out some new products with some promise and decided to try this.
I like how it feels.Solidly built, comfortable.
Dust collection seems good, even better with vacuum attached.
Quiet operation.
Very low vibration.
Nice carry case, except i don't like the limited sand pad storage.

--This thing leaves swirl marks. -- More like "edge lines" from the two inner rings rotating in opposite directions.I know this isn't always a factor when just wanting stock removed before sheet sanding, but its still irritating.The limited suppliers of sanding disks and the swirling leaves me wishing I would have stuck with Dewalt Porter cable Makita, or Milwaukee.Anyhow It's still solidly built, comfortable, and does remove stock well, but I'll just have to use my nice Dewalt 1/4 sheet sander to chase all the lines left by the Rockwell orbital...

Hope this helps-

Sand up to Twice as Fast with Half the Vibration
This Rockwell vibrafree sander increases productivity while keeping feedback vibration low. It works like those well-known noise-cancelling headphones that record the noise and play back an opposite signal to cancel the noise. With other sanders, high levels of vibration can mean the sander is not in contact with the work surface at all times, which translates into wasted time and energy. Those same high levels of vibration can also be delivered directly into your hands, causing discomfort and more downtime. Tool vibration can lead to serious problems for professionals. After only a few minutes, vibration causes loss of sensation in the fingers and hand, and it can take hours to recover. Following hours of use, recovery can span several days. And continual exposure to vibration can culminate in HAVS (Hand Arm Vibration Syndrome), a severe occupational disease that may cause disability and lead workers to lose their jobs.

Thankfully, active vibration cancelling technology is what seperates this vibrafree random-orbit sander from the pack. It is uniquely designed with two counteracting sanding pads, so the vibration is redirected back into sanding, instead of into your hand.
Sand Faster and Safer
To prevent these kinds of vibration-based problems while simultaneously increasing efficiency, the RK4245K Sander features Vibrafree sanding technology. With traditional sanders, part of the spin goes into the vibration rather than the sanding. With the RK4245K, two counter-acting sanding pads move in opposite directions so the sanding vibration is re-directed back to the sanding instead of onto your hands. Previously wasted motion is thus channeled into sanding, effectively doubling the material removal rate.

Cleaner and Healthier Work Environment
This sander comes equipped with a Cyclonic dust/air separator to remove 50% more dust than other sanders. This system uses centrifugal force to separate the dust particles from the air and trap them inside a transparent dust box, making it easy to monitor fill rate.
And unlike cloth bags, the box never clogs, loses suction, or wears out.User-Friendly Features
Powered by a motor built in-house for better power and efficiency, the RK4245K has great features. An aluminum base ensures flatness and durability, while a dust-sealed switch prevents premature wear. For reliable comfort and control, this sander also has a soft, anti-slip grip area, and a pad brake that reduces swirl markings or scoring to the workpiece.
