I've never used a sandblaster before. This was easy to put together and use, just cover up all your skin/ head. It uses way less sand than I thought I would go through. I blasted a barbeque (not recommended) and only used about 2 or 3 pounds of sand I'd guess, so a 50 lb bag goes a long ways. The play sand form Home Depot clogged occasionally with a large rock, which is easy to clean out by unscrewing the tip, and removing the particle, takes about 10 seconds.
NOTE: my dual chamber compressor is not large enough to run this thing. I think it has two 2.5 gal tanks. Here's the problem with small compressorsmoisture. The more the compressor runs, the more moisture the builds up in the compressor and lines, especially in humid climates, and even here in dry Boise it was too much. The water clogs the sand and it won't work. I had to run to Home Depot and get a moisture filter/ remover that hooks on just before the tool, it's pretty small and doesn't really get in the way, about $12. The filter did get some water out, but it was not good enough and the tool still clogged up. I barely got through the job, but I think I'd only use this on a very small job with my small compressor and figure on it clogging after about 5 minutes. I'd have to take it to a buddy's house with a larger compressor if I wanted to do a larger project.
It seemed to work pretty good doing my project on the grass, some sand is good anyhow to help loosen up the grass. Just put a tarp under your project to catch any larger pieces/ most of the sand. I wouldn't try re-using the sand (has junk in it).
CONCLUSIONget it if you have a large compressor, although you may still need to buy a $12 moisture filter (as noted in the instructions), especially in more humid climates.

Draws media well, especially with shortened hose. Reasonably comfortable grip and trigger. Metal threaded tip (chrome end piece in photo) fits fairly poorly with gun body -it doesn't leak air, but the threads scrape loudly. Problem was cured with a stiff steel brush. Gun disassembles well -metal tip, ceramic tip and o-ring, and front assembly all come apart easily. Didn't take the trigger apart. I wouldn't want to strip the paint from a car with this setup, but for smaller items (exhaust manifold, small steel pieces) it works very well.

i purchased this product because i was sandblasting some paint off of the walls in my basement(concrete walls) and it did work...somewhat...it would have taken me six months to get it all off so i ended up just painting over it. the gun gets clogged alot with bigger mil sand.(i was using black beauty)but the price!!! it would have cost me 150 a day to rent a sandblaster from the rental places around me. so it was well worth it especially if you have your own compressor..JUST SO EVERYONE KNOWS AHEAD...THIS GUN DOESNT COME WITH A QUICK CONNECT FOR THE COMPRESSOR. had to go out and purchase one seperately.

I bought mine from a brick and mortar store for about 6 dollars more than Amazon. The blaster used less air than a couple of my air grinders. My compressor is a Quincy 5hp that turns on at 145 PSI and off at 175. The blaster clogged about every 10 seconds when I ran it at 145 to 175 PSI. I put a regulator on and set it at 90 PSI. At 90 PSI it NEVER clogged again, and blasted very well while holding the gun 1 to 4 inches away. The directions said to not use higher than 125 PSI. I should have read them before I started. Also, don't push the hose onto the pickup tube until it hits the outer tube. That will keep air from entering between the tubes and will cause it to not pickup sand. I blasted 8 hours without a problem after lowering the pressure. All sand blasters take a lot of air, but I don't think you need one as big as mine to use this.
WOW, this thing is an air-hog. The box says 9 CFM @ 90 PSI and I believe it. This tool will bring any 120V compressor to its knees if you try to run it flat-out.
I was using it to blast the underside of my Jeep with Quickrete play sand. The sand fed great at 90 PSI, started to sputter around 80 PSI, and basically stopped working at 60 PSI. I have a 2.5 HP Ingersoll Rand compressor that claims to do 6.4 CFM @ 90 PSI. Boy was that a lie. I was getting literally 20-30 seconds of decent blasting (basically the time it took to bleed the 20 gal tank from 110 PSI down to 80 PSI), then I'd have to stop and wait several minutes for the compressor to catch up. I even added my 7 gal portable tank into the mix at one point to buy myself a few more seconds with the extra volume.
Richard J. Kinch has a great page called "Evaluating True Horsepower and CFM Ratings of Air Compressors". After reading that, I did the experiments with my compressor and found that it was actually only putting out 1.4 CFM @ 90 PSI. Talk about frustrating! DON'T TRUST MANUFACTURER COMPRESSOR SPECS!! Needless to say, a new compressor is now on my wishlist. And I'm not going to buy it unless they let me fire it up and stopwatch its cycle-time first.
Kinch was also a bit of a depressing read. He explains that there simply is not enough energy coming out of a 15A 120V outlet to generate more than about 6 CFM at 90 PSI, and that's with a two-stage compressor in a perfect world. After you account for the various inefficiencies and losses, the best-case is really about 3-4 CFM at 90 PSI. Given the knowledge that it's physically impossible for a 120V compressor to keep up with 9 CFM @ 90 PSI, the best setup for this tool would be a high PSI compressor with an adjustable "cut-in" point, a large tank, and of course the highest CFM you can get. If the compressor will do 150 PSI and you can set the cut-in point to, say 125 PSI, you may be able stay out in front of the 90 PSI mark. Assuming you're taking natural pauses here and there while blasting, AND that your compressor and power source can handle 100% duty cycle.
This blaster may also preform better at a lower PSI with finer media. The play sand was nice and clean, but a little coarser than I expected. Still, it barely made a dent in the rust and road-grime. I suspect that anything finer would have just bounced off of my project.
Also, forgot to mention that the first thing I did after opening the package was cut the siphon hose down from 10' to 5'. Not sure if that helped or hurt since I didn't test it before hand. Intuitively, it seems like it would help. Also tried converting the siphon from a pick-up tube to a gravity feed set up at one point by attaching the hose to the bottom of an open bucket. I couldn't get it to feed at all. Still seems like a sound idea, just didn't have time to sort out the details that day.
Also, also, this tool will REALLY expose any water contamination problems in your compressed air system. The crappy little water/oil separator I had wasn't doing a thing.
Giving up on the blaster for now and trying a needle scaler instead to knock the big stuff off.
FOLLOW-UP: The needle scaler was DEFINITELY the way to go for my project. Spent about 2 days going at it with a scraper and a knotted wire cup, got about 15% done. Spent a full day going at it with this blaster, got another 10% done. Spent 6 hours with the needle scaler and got the remaining 75% knocked out. Live and learn.
