In-Depth Review: Black & Decker BDERO100 Random Orbit Sander, 5-Inch
The Black & Decker BDERO100 is something I used to get my porch refinished. I was glad to have this sander around because of how fast it's able to do its job. According to my own personal experience, it's able to sand down bare wood so that any dirt and dents through the years are easily grinded down to smoothness.
It's a worthwhile buy in light of its price tag for sure.
Here are the alternatives to the Black & Decker BDERO100.
1) Bosch ROS20VSC Random Orbit Sander with Carrying Bag, 5-Inch, Blue
The Bosch ROS20VSC shares several specs with the cheaper Black & Decker BDERO100, notably its 5-inch disk, its 4.5 rating on Amazon, and the fact that they're both random orbit sanders. However, the Black & Decker unit is smaller than the Bosch unit, thus justifying its nearly halved price. What's more, the BDERO100 weighs about 0.3 pounds lighter than the ROS20VSC.
What's more, the Bosch ROS20VSC Random Orbit Sander is arguably the more complete package with its inclusion of a carrying bag. It also lists its orbits per minute or rotations per minute as 7,500 to 12,000 OPM. Meanwhile, the Black & Decker BDERO100 also offers a non-variable 12,000 OPM, so at least with the Bosch unit you get more variety with your orbits or sanding. These units are pretty close together in specs save for the Bosch sander being slightly bigger, heavier, and with more of a speed range.
2) PORTER-CABLE 382 5-Inch Random Orbit Sander
There's only the slightest of price discrepancies between the PORTER-CABLE 382 and the Black & Decker BDERO100 Random Orbit Sander. They're both 5-inch disk random orbit sanders, with the PORTER-CABLE 382 edging out the cheaper B&D unit with its heavier 3.6 pounds of weight and its slightly bigger dimensions compared to both the BDERO100 and the Bosch ROS20VSC.
On the other hand, the ROS20VSC, BDERO100, and 382 all share the standard 12,000 OPM. However, unlike the PORTER-CABLE 382 and the Black & Decker BDERO100, the Bosch ROS20VSC actually has a wider range of speed, going from 7,500 to 12,000 OPM (both the B&D ad Porter-Cable instead have single-speed non-variable units that can only go from 0 to 12,000 OPM).
3) PORTER-CABLE 7346SP 6-Inch Random Orbit Sander with Polishing Pad
The PORTER-CABLE 7346SP may have you question which spec is more important, the larger 6-inch disk size or the slower 6,800 OPM compared to the standard 12,000 OPM found in the rest of this list. Compared to the way more affordable Black & Decker BDERO100, the 7346SP leaves much to be desired in terms of orbits. It's also way larger than the Porter-Cable 382, the Bosch ROS20VSC, or the B&D BDERO100.
However, there's a reason for the discrepancy and faster OPM isn't necessarily better. As you may recall, slower standard orbital sanders are best used for the final sanding. In light of that, the slower 2,500 to 8,500 OPM is probably more suited for finishing sanding jobs while still retaining the random orbit sander ability to aggressively sand down rougher patches.
4) 3M Random Orbital Sander 20317, 5 in Non-vacuum 3/16 in Orbit, 1 Per Case
The 3M 20317 Random Orbital Sander is easily the most expensive random orbit or orbital sander on this list. It's also the lightest sander featured on this article, although its compact size is similar to the Bosch ROS20VSC but beaten by the Black & Decker BDERO100 (which is actually the smallest sander in terms of size). For something so light, it packs the standard speed of 12,000 OPM. Should something so light have such a high OPM rate is left?
I leave that to the opinion of the users themselves (although it's understandable if you have trepidations in regards to vibrations or to the 3M sander being too light to handle its powerful motor). On one hand, it gets high marks on Amazon.com with high rating and positive feedback on its superior mobility compared to others.
5) DEWALT DWE6421K Random Orbit Sander Kit, 5"
The DEWALT DWE6421K is the third most expensive unit on this list (next to the 3M Random Orbit Sander 20317 and the PORTER-CABLE 7346SP). With that in mind, does it pack more bang for your buck or more value for your investment? Compared to the Black & Decker BDERO100, it's quite the hefty random orbit sander, weighing 4 pounds instead of 3.2 pounds and being wider, taller, and lengthier all around than its smaller B&D counterpart.
It has the standard single-speed 12,000 OPM speed running on an impressive 3-amp motor, but the Black & Decker BDERO100 has a more powerful 5-amp motor itself that ensures more torque for every orbit. Meanwhile, only the 3M Random Orbital Sander 20317 is better in terms of ratings because the DEWALT DWE6421K has earned a high score from a respectable amount of customers.

The Final Cut
For a petite sander, the Black & Decker BDERO100 brings more value for your investment pound-for-pound. It's a worthwhile buy in light of its efficiency, compactness, cleanliness, and convenience. It has the standard diameter size of 5 inches and it only weighs about 3.2 pounds, which makes it easy to move around manually. Maneuvering this unit is straightforward and user-friendly due to its lightness, ergonomic handle, and versatility in sanding down various work pieces and stock. I personally had no problems with the dust bag although I've read reviews that can't stand using it.
