    Great Product, glad I selected this model
    I have used this for a variety of jobs, including touching up the edges of a sanded floor, and modifying trim to fit out of true spots. It works exceptionally well for floor edges due to its unique design, it is lightweight and easy to use on other projects.

    The smaller front drum enables the sander to fit into tight spaces and get close to floor edges. If the front door is lifted, it can get even closer (but be careful). The belt adjustment is easy, and needs less tinkering than the last sander I owned, which had to be adjusted constantly.


    The only down side, and it is a small one, is that the inner workers fill up with sawdust often, and should be emptied every 10-20 minutes. (open belt assembly installer, open front door, hold sideways and gently tap). AS with most tools with a catch bag, very little sawdust actually goes into the collection bag.

    Poor Instructions
    Just bought it, and so won't evaluate its performance, but the instructions, all one and one-half pages of them, are nothing but drawings with arrows - not a word on them. So don't count on them to figure out the adjustments.

    Great Belt Sander with lots of power and lightweight.
    Really impressed with the power. lightweight. adjustable handle. Compact size. The front nose can get into tighter areas. The sawdust really goes into the bag. U can adjust the belt with ease. I've sanded a deck,picnic table and bench the 1st 2-days I had it. Handles very easily, just let do the work. Well ballanced!! It's worked out great. My arms were'nt sore after handling it all day!! I liked what I saw, when I researched for a new belt sander. Very glad I gave this one a try!!!

    The weight and size. The dust collection. The smaller front end and the power. Adjustable handle!! How close you can get to the walls, really great.


    Maybe needs a bigger dust bag, as it does collect the dust well. Everything else is perfect!!! How about a carrying case!!!! It's small enough!!!

    This is a real workhorse and works extremely well.
    I'm installing hardwood flooring in our home and have had to use cement floor leveling compound to level the subfloor. The leveling compound requires final sanding and the "Dragster" has been up to to the job to do a tremendous amount of sanding. The sander works like a beaver.

    The sander has plenty of power to handle everything I've thrown at it and the ergonomics are outstanding. The small nose wheel allows sanding extremely close to a wall or an obstruction. This feature alone makes the Dragster well worth it.


    I have not found any "cons". This is my second belt sander and the design makes it far superior to my first one, which was a standard design, with equal size wheels at both ends.
