Review: Great compressor - This was a great purchase. Very quiet, recovers fast. I added an extra 20 gallon air tank with no issues. I highly recommend this unit. I use it for hobby automotive and light carpentry
Review: Not "Ultra" Quiet, but quieter. - I've had two of the 4-horsepower units for about 3 months. Working fine so far. I only gave them 2 stars for the reasons I've detailed below. The "ultra quiet" advertising annoys me. Yes, they are quieter than a traditional compressor. The 8-cylinder design changes the heavy "feel it in your stomach" pounding of a conventional compressor into more of a purr, which is not only quieter, but also less intrusive. But you still have to wear hearing protection. My family appreciates the lower level of sound coming from my shop, but you can't hold a conversation around these. In my opinion they don't deserve the "ultra" claim--yes they are better, but not ultra better. The manual tank drain is annoying. First, the handle on the drain valve is microscopic. You're reaching down under the tank, blind, trying to get your hands on a little piece of plastic. Second, when you activate it, the blast of air from the tank comes right by your fingers. Getting hit with that kind of air blast is dangerous. This is just poor design. I addressed this by taking a piece of wooden closet rod about a foot long and cutting a notch in the end, such that it fits easily over the little plastic handle on the drain valve. With this, I don't have to reach under the tank, and my hand is a foot away from the air/water blast. The pressure regulator knob takes a crazy number of turns to adjust. From full off to full on means twisting the knob 32 times. And there's no shutoff valve, so if you want to reduce the output to zero you have to untwist the knob 32 times, and then to get pressure back takes another 32. And then take a nap to rest your hand. On the plus side..... The packaging is outstanding. They arrive on a sturdy standard size 40" by 48" pallet. That's covered by a super-heavy cardboard box that leaves at least 6" of air space around the compressor, so even if the trucking company bashes the box, there's a chance the compressor won't be impacted. In my case, the cardboard was in great shape, and so was the compressor. Depending on where you live, of course, you may get a different trucking company. The compressor works: it compresses air. I don't know about the 10 CFM claim, but it certainly charges up the tank in short order. Bottom line: Less noisy than conventional compressors. Moves plenty of air. Is corded, so it's not permanently tethered to one place. Has a nice look to it. Not having to change the oil is a blessing. Would benefit from having a shut-off valve. Would benefit from having a different pressure regulator.

### ⭐⭐⭐⭐ Super quiet compressor for a personal workshop
*by T***. on March 8, 2023*

The noise level is something else. This replaced a large standard style compressor that I wore hearing protection for when working in the shop if it was running. Now you can have a normal conversation. Tank is small but the system is basically designed to run on demand, I've never run out of air operating my vapor blaster or anything else. BUT it's like the outsourced the painting of the tank to children. I've only had this for a year, it lives in a heated & cooled garage and the paint is just flaking off every weld on the tank and getting rust. I'm going to have to remove the motors, strip it and repaint it to avoid it turning into a pile of rust.
