Good Product but design could be better
nice little unit! design could be improved bit by extending the threads on polishing and abrasive wheel to give you enough room to use it with out the belt or the motor getting in the way but overall works as intended. price is good tho

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!

Nice and small
I do guitar repair and don't have a lot of space this thing helps me with sanding nuts and saddles saving time and money

DISAPPOINTING GARBAGE
The whole thing rattled and vibrated as soon as it was turned on. When I would turn it on, it kept stopping and starting over and over. The motor wires connecting it to the switch are crossed making it impossible to get the motor cover on. Very disappointing.

Too small for normal-sized humans.
Works well. Ergonomically - a nightmare for a human. Would be great for dwarves. Wound up using two of them to split the duties between the two wheels - using both on one machine spells disaster for your hands. At least it is cheap enough to buy two.

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.

🧨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!

Great starter tool
I don't normally write reviews. I was impressed with this tool. It is small and limited to only certain grit belts. But I didn't get it for metal working. I was looking for a knife sharpener. This fit the bill. Just messing around with it a sharpened 3 chefs knife in a half hour. Razor sharp? No. The knives were pretty dull. What I liked: Easy to change belts. Really good adjustable power. Set 15 degree for perfect angle. I would recommend if you are looking for a low budget sharpener and your a novice with powered belt grinders for sharpening knives.

It’s OK, but it’s cheaply made, but it still serve the purpose

Not strong enough for what I need

Must be bolted down before use. Can only use for smaller knives or jewelry etc. The buffer does a great job also.
