## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Compressor So Far
*by T***N on May 31, 2024*

This replaced an old 2HP compressor in my shop. This builds pressure super quick, is super quiet and is working flawlessly so far. I have it hooked up to an IR Air Dryer and I run both drain valves into pneumatic sintered silencers and into a gallon jug to catch the bleed off since I don't want to route it outside for my neighbors to hear. It's a quiet setup and works wonderful for my milling machines and blast cabinet!

### ⭐⭐⭐⭐⭐ Oil Free Air Compressor
*by D***Y on November 28, 2023*

Limited maintenance needed. Works well for us in small lab/workshop space. Plenty of capacity. Not as loud as traditional upright compressors. Highly suggest you get the auto drain feature. Works well to keep the moisture out of your equipment. Easy to move around if needed

### ⭐ Awful Product and Customer Service Experience
*by I***Y on December 27, 2022*

This order was mishandled from the start. I ordered this compressor to have a low power/low noise air supply for LVLP finishing. The compressor arrived and would not start. After providing the serial number and QR code associated with my particular machine, the customer service representative repeatedly assured me that the compressor had been checked and was running at the warehouse. Upon closer inspection, I found a set of wires hanging out near where the start capacitors should be. They never installed the start capacitors! Not sure how they had the machine running at the warehouse without the pats required to start the compressor. The customer service rep said he had to send an entire new unit (from California, I'm East Coast). I lost a ton of money on two jobs and put out sub-par finishes that will ultimately reflect poorly on my brand.Returning the other compressor was a nightmare. It sat on a pallet taking up space in my shop for nearly 6 weeks because California Air Tools couldn't coordinate with the freight company for a pick up. I was told that it was being picked up on a Friday from 11-3. I received a phone call from the freight company during that window to schedule a pick up. As it turns out, CAT emailed the freight company 30 minutes before to schedule the pick up. Not how that works.Within a week the welds on the exterior of the machine had started to rust. The machine, after light use, has started to get noticeably louder. So very disappointing!I was told I would receive a free air hose to compensate me for the inconveniences. I never received it and when I asked when the air hose would arrive they acted like they had never offered.In Summary- Compressor arrived missing parts- Customer service lied about working status of machine- Customer service was unable to efficiently handle return/replacement logistics- Compressor started to develop rust within a week- Customer service did not make good on compensation offerThis company has a lot to figure out. I cannot endorse this product nor the way in which the customer experience was handled.
