Honest answers

Every critical review we have received · quoted whole

Every complaint, and what we would have replied.

Each one is quoted whole, in the language it was written in. Under it: whether we think the reviewer was right, and a plain test for whether their problem would also be your problem. That test matters more than our opinion — if the answer is yes, we would genuinely rather you didn't buy.

“Nothing came off my wood” THEY ARE RIGHT — AND IT IS OUR FAULT

GERMANY · 7 FEBRUARY 2026 · VERIFIED PURCHASE

“Works rather poorly than well. The task was to make the surfaces pretty again. Apart from a lot of noise and dirt, almost nothing happened. Very disappointing. I do like the concept, but if it doesn't work it was simply a waste of time.”

He is not wrong, and we are not going to blame him for it. He used the machine on soft, flexible wood to make it smooth. Abrasive bounces off a surface that gives way instead of biting into it — he would have got the same result from any sandblaster on the market, ours or a €3,000 cabinet.

The mistake happened before he switched it on: our listing let him believe this was a sanding machine. It is not. It strips hard surfaces and leaves a profile behind. That cost him a weekend and €399, and it cost us a two-star review we had coming.

DOES HIS PROBLEM BECOME YOUR PROBLEM?

Yes — if you want to smooth soft wood, plywood, or prepare for paint. Then he is describing exactly what will happen to you. Buy an orbital sander, around €80. We mean that.

No — if you are stripping rust, paint off stone, or texturing hardwood. Different material, different physics. His review says nothing about your job.

SAME MACHINE, SAME COUNTRY

“Fantastic machine! It works extremely fast — even better than my sandblasting system with a compressor. Congratulations!”

“Only works with exactly the right abrasives” TRUE. IT IS THE WHOLE GAME.

FRANCE · 27 MAY 2026

“Brilliant product, easy blasting without having to make adjustments in every direction. On price it is worth it, because once you add a compressor you go well past this with a classic blaster. You do have to use the right recommended abrasives, otherwise it doesn't work. The machine sprays a bit wide, but that is the price of a simple, fast tool. Great for one-off jobs. I recommend it!”

Olivier put his finger on the single thing that separates our five-star reviews from our one-star ones, and he did it in one sentence. Wrong grain size, wrong hardness, or damp abrasive, and this machine looks broken. The right abrasive, and it does in ten minutes what a compressor setup does in an hour.

Somebody who buys the wrong bag is not careless — we simply never made the choice obvious enough. A tool that only works with the correct consumable has to sell the knowledge with it, and we didn't.

DOES HIS PROBLEM BECOME YOUR PROBLEM?

Not any more. Pick your material in the grit guide and you get the exact abrasive, grain size and flow setting. What grit to use? →

Yes, if you plan to run whatever sand you have in the shed. It will not work, and no amount of build quality will save it.

SAME LESSON, PUT TO THE TEST

“Good results straight away on a garden chair, paint on a stone garden stove, and rust on an old spade. Much handier than a compressor with a blasting gun. I tested both glass beads and coarse aluminium oxide grit — the latter clearly gave the best result.”

“It clogs, and I couldn't reach anyone” THE ONE THAT SHOULD NEVER HAPPEN

FRANCE · 6 JULY 2026

“Electric blaster that doesn't work, it clogs regularly and blasts nothing. Bought for €539 with a bag of sand. PS: I asked Amazon for a refund — still nothing.”

This is the review that hurts most, because a genuinely defective unit is exactly the case the rules cover. A motor or a feed can fail — it happens to Hilti and Bosch too, and we are not going to pretend our failure rate is zero. A defective machine is covered by the legal warranty, and for defects the return shipping is on us. What decides whether a failure becomes a one-star review is what happens next — and on a marketplace we don't get to be part of “next”. Her request went into a form and stopped there.

And if a machine clogs rather than breaks: that is almost always damp abrasive or a worn blast wheel — the wear parts Paolo describes below, and a swap we will walk you through. Clarisse, if you ever read this: mail us. A defective machine is covered, marketplace or not.

DOES HER PROBLEM BECOME YOUR PROBLEM?

A unit can fail. That risk is real and we are not going to claim otherwise.

Being left with it is not. Buy here and a failure is a mail to a person — not a form that goes nowhere — and a real defect is covered by the legal warranty.

WHAT IT LOOKS LIKE WHEN WE ARE REACHABLE

“It is necessary to replace the parts that wear out in time: blast wheel, ring and hand protector. Excellent management of spare parts by the seller, very professional.”

The line behind half the bad reviews

It is a sandblaster, not a sander.

If you only read one thing on this page, read this. The most damaging review we have ever had comes from one mistake, and it was ours to prevent: people bought this expecting a sanding machine. It strips hard surfaces. It does not smooth soft ones.

What it is built for

Rust off metal — gates, tools, engine parts, garden furniture
Paint and coatings off stone, brick, concrete
Weathered texture into hardwood, oak beams, shutters
Spot repair and small parts, where masking a booth makes no sense
Etching glass and ceramic

The job in one word: stripping. It removes what is on top and leaves a profile.

What it will disappoint you at

Smoothing soft wood — pine, plywood, anything flexible
Large flat surfaces — a facade, a car body, a floor
Cheap running costs — the abrasive is single-use, so grit is an ongoing consumable
Indoor work without containment. It makes dust, all blasting does
Fine finishing before paint — that is an orbital sander's job

If that is your job, buy a Bosch or DeWalt orbital sander instead. We would rather lose the sale than read about it afterwards in a review that never hears back.

What the marketplace takes away

There you get a form. Here you get a person.
