Review on HOLDWIN Blasting Carbide Sandblaster Stainless: Efficient Cleaning and Durability Combined by Doug Virden

We tested the gun as it was delivered. That does not work. The gun came with a piece of Teflon wrapped into a rough ring (sort of) that stuck behind the tip and nozzle assembly. It was useless from what I could see. I found that when the cannon was activated the venturi effect would pull the nozzle back towards the air hole which then killed the venturi effect. The nozzle is inserted into the tip of the gun and nothing prevents it from moving backwards. I went through all my hardware junk and found a washer that would fit the tip of the 0.D gun. and which also had an inside diameter slightly smaller than the nozzle diameter. Now that the adjustable air connector is all the way up front, the washer will hold the ceramic nozzle insert and the gun will work fine. In summary, it is ridiculous that this vendor is selling a non-working item. Either the build is missing parts, inconsistencies, incorrect parts, or they just don't care that the gun doesn't work at all.
