Built solidly, easy to use.
Works just like a belt sander should, only in miniature. My hobbies deal with building, modifying small parts. This is perfect for that. The seven speeds really help. Slow speed helps prevent melting plastic and the choice of belt grits is great. It is belt solidly and should last a long time. Super easy to change belts and it has pretty good power for a small motor. It hasn’t bogged down yet. It runs smoothly and is quieter than most of my tools. Overall a good little work horse. Glad I bought it.

Great price and good quality.
I watch way too many knife-making videos, and let’s be honest—I have absolutely no idea what I’m doing. But hey, I justified my purchase with the classic excuse: “I can use it to sharpen my lawnmower and tiller blades, and all my knives!” As a novice’s apprentice, I’m basically the awkward kid in shop class who can’t figure out which end of the hammer to hold. So, I decided to buy the Model 1, 3-in-1 Mini Belt Sander. I don’t know why I was nervous about using it; it seemed simple enough. Well, the buffer and sander are pretty self-explanatory, but that grinding wheel? Let’s just say it takes a bit of getting used to. I tried it on a machete, and let’s just say my grinds looked like they were done by a toddler with a crayon. But hey, practice makes perfect, right? Bottom line: my limited knowledge doesn’t exactly qualify me to judge this product like a master craftsman. But as someone who values their hard-earned cash, I can confidently say this is a great product—perfect for any budget and compact enough to squeeze into my cluttered garage, which I like to call my “wannabe workshop.” I’ve been using it consistently for the past month, and it’s still holding up like a champ. So, if you ever need a sander that can handle a novice’s mishaps, this one’s got your back!

The little sander that could
I use this little sanding belt for leather edge work and it has improved the quality immensely. I love how it makes my process faster while not sacrificing quality.

Fun to Use -- Decent Quality
I have had this tool for 6 months and it has been fun to use. It gets "only" three stars because it is limited in the application lacking power--but that is what one should expect with a tool like this. I like its versatility--grinding, shaping and polishing small objects. It doesn't have a great build quality, but certainly good enough for the price.

Not worth
This sander was way too small and is very low quality. It’s not very safe as it doesn’t sand well. It very loud compare to my old sander and overall it was just a bad experience using it.

Works well
Does exactly what I need it to do. Love the fact that the speed settings go up pretty high and it stills stay stable on the table. Very powerful I purchased for resin.

🧨Wow!🧨
This little guy is perfect for small projects! It works perfect for me. Good power. Good speeds. Easy to put together. You can’t beat the price either, you get a lot for your money. It’s like the ole saying…. “Dynamite comes in Small Packages!” It was mind blowing for me, for this product to be as great as it is!

Underpowered and Tiny
Includes everything it says but is so small and underpowered any amount of pressure bogs down the motor making it useless
