Great Blaster
Stancel•October 7, 2017
Would have gotten 5 stars if it wasn't missing the axle for the tires. Used with quickrete play sand and it worked great. Not a single clog.
Perfect - easy to use

Perfect - easy to use. The product did arrive missing a piece, but the company immediately sent out the part as soon as we called them. My son and husband are having a great time blasting everything they can find with rust on it.
Exceeded my expectations and fulfilled my needs nicely. JUST BUY IT.
The Mad Inventor•September 22, 2017
It looked much bigger in the picture than in real life. When it arrived, I was surprised how small it was. But it will hold an entire 50 lb bags of media, or full 5 gallon bucket worth.
Assembly was easy and took 10- 15 minutes just by looking at the picture on the box. I expected a lid, something to keep debris and leaves out, but no such luck. Based on what I saw on youtube, this unit performed much faster than I expected. Apparently the guys on youtube had smaller compressors, maybe 7 cfm?
My air did not have a dryer. I have a 80 gallon 18scfm compressor and with that much flow, and the right media, the rust really disappears quickly. Going through paint is 2/3 slower. Going through paint you will use a lot of media.
Aluminum oxide 80 grit ($25, 50lbs from tractor supply) worked really well but left the metal with a semi rough surface after the rust or paint was removed down to bare metal. Aluminum oxide is $10 cheaper per 50lbs than glass media, and its 25% faster at removing rust and paint, although it leaves a rougher finish, which will be ok on some projects, and not acceptable on others.
Glass media 80 grit ($34, 50lb tractor supply) left a much smoother surface, better for repainting if you want a smooth finish on your paint job when your done. Glass media was 25% slower at removing material than the aluminum oxide was. But it definitely left a smoother finish and it was more thorough at removing debris. There will certainly be times the extra cost and slowness will be my preferred removal media for the preferred finish.
I tried black diamond 30-60 grit and it would only shoot from the largest nozzle. It did remove material, but was much slower than the other medias. It was also much cheaper at $8.50 per 50 lb bag. I didnt like it. It wont get down in the nooks and crannys of pits to remove all rust. It only works on smooth surfaces and it bounces around a lot more while shooting. Also the material it did remove, was less effective as it left behind more rust and debri it just didn't seem able to dislodge. Its removal effectiveness was much sloppier.
The spray gun was surprisingly effective. It came with four different sized nozzles which change out quickly and don't need tools to do so. I tried every nozzle size on each of the different medias. I'm glad it came with different sized nozzles, as each of the different medias had its own preferences for what nozzle it would shoot well out of.
When I was assembling it, I looked at the outlet tube at the bottom of the tank and saw a hole in it the hose would not be able to close up. My initial impression was it was junk with poor engineering and I expected poor performance from this unit. But to my surprise it performed flawlessly for me. I did make sure my media was dry.
The glass media, although I opened it from a sealed plastic can, seemed a little damp to the touch. It seemed a little clingy. To my surprise it did shoot well out of the gun with the air flow although it did stick slightly to the interior of the nozzle. But it did not clog the gun or nozzle. However the glass media did not settle well to the bottom of the tank although it did flow well through the outlet pipe at the bottom. I would fill the tank with glass media and a one inch cavity would develop above the outlet tube. Any glass media perfectly directly above the outlet tube would fall down and out the tube and it did shoot well. However, any glass media not directly above the outlet tube, stuck to itself and would not fall to the bottom till we shook the tank, or reached in and knocked it loose. I cant blame the blaster for this. But the glass media was a bit tacky and not free flowing like the aluminum oxide or black diamond slag media.
If I had a lot of need to use a lot of glass, I would examine how to attach a vibrator to the bottom of the tank. I'm also wondering if I can dry the glass media out further by placing bags of desiccant inside and leaving it there to further remove moisture.
The hose from the bottom of the tank to the gun seemed a bit short at 7 feet. But since the tank rolled around easy enough, it really didn't seem to be much of a problem. Expecting this to be a problem, I bought another 30 foot $53 piece of hose from ace hardware. The longer the hose, the longer it takes the media to go from the tank to the gun. The 7 hose had a 15 second delay. The 30 foot hose had a 45 second delay. But once a hose is primed, then there is no delay each time you pull the trigger.
Realizing the moisture content of media will play a big part in the blasting effectiveness, I have purchased a $10 moisture meter so i can measure with precision the moisture content of medial before i buy it, and how the moisture changes in my different media storage situations. Alotpower Soil Moisture Sensor Meter,Hygrometer Moisture Sensor for Garden, Farm, Lawn Plants Indoor & Outdoor(No Battery needed) I will also be able to tell how much moisture the media left in the pot has absorbed while being stored in it. I expect there to be a point it will absorb moisture from sitting in the open pot in my high humidity FL where I will learn how long I can leave it in the pot, and when to remove it and put it back in the sealed buckets.
The down side: The hose smells awe-full. I cut off a 1 inch piece to take with me to Ace to buy more hose of the same, and it stunk up the car and I had to crack the windows to stop the smell from getting worse. But since this is a took I use outside, I wont hold the smell of the hose against it.
I like this unit very much. I would recommend it to anyone not wanting to spend a thousand on a professional rig, and I would buy it again.

Not the best but works over priced

Cheaply made flimsy but works. Over priced. Wheels wobble.
Five Stars
