T32336 Compressor from Grizzly. It took three tries to get one that ran. First two had failed pressure relief valves, causing the cylinders to remain loaded after first pressure cycle. It would attempt to run next cycle and pop the circuit breaker. Grizzly compensated me with a gift certificate for that hassle - good on them. The third machine only ran for 13 months (one month past warranty expiration) and had only about 25 hours of total operating time. In mid-cycle, it started clattering badly. Sounds like something came apart in the primary cylinder drive assembly. Grizzly Customer Service refused to compensate me in any way, telling me to contact the manufacturer (Mega Compressor). I'll have to rethink buying anything more from Grizzly (I have their table saw, planer/jointer and dust collector - all good, but bought many years ago). Has their quality control and customer care fallen by the wayside? Could be. Good luck. Wrote a review on their website including the above. Not posted. Apparently a dishonest company, as stated in another review on Trust Pilot.UPDATE 9/29/2022: I have now disassembled the machine and found it to have failed from (yet another) manufacturing defect. The screw that secures the pressure plate and piston ring to the piston head failed (fractured) in what appears to have been a fatigue crack that was likely due to either it being defective (cracked) upon insertion or over-torqued when it was installed. This left the pressure plate at the top of the cylinder and the piston head flopping around within the cylinder. I have been in contact with Mega Power in Texas, the "manufacturer" (actually it's made in China, as seen on the machine label) and received a quote of $2.50 per M6-1.00 x 16mm screw, plus $17.00 for shipping and handling, plus a 4.5% charge for using my credit card. The screw in use is stamped "HUA 10.9", meaning it is a high tensile strength, Class 10.9 screw. Problematically, the screw is black oxide-coated steel, which is corrosion-resistant only in dry environments. There was some rust on the head of the screw, but this was not the cause of failure. These same black oxide steel screws are also used on the exhaust port lock block (atop the upper valve plate), in a recessed hole that holds water that is condensed during compression operations. These screw heads were badly rusted, but I cannot predict the impact this might have on the life of the machine. The inside of a compressor is NOT a dry environment, and these screws should not have been used. Rather than reassemble the machine with these same, corrosion-prone screws, I opted to purchase zinc-plated Class 10.9 screws for the pressure plates and 18-8 stainless steel screws for the exhaust port blocks from McMaster-Carr (available only in packs of 50) for about $0.15 per screw plus a reasonable shipping charge. The machine is now up and running quietly again. My advice to the Grizzly shopper in all of this is as follows: If you buy a Grizzly compressor, be sure to operate it for at least 40 hours within the warranty period in hopes that if it has a defect such as this it will fail while you are still covered by the warranty. My advice to Grizzly Industrial: Hire some engineers to look closely at how the products you want to sell are manufactured, or better yet, specify how a machine is to be manufactured to meet Grizzly requirements. This could result in a better product and a far more satisfied customer. Buyer beware.
