This compressor was easy to install and wire. The phone app is easy to use but a little glitchy. Also, it's not great that the system doesn't "maintain" the last setting. The phone app has three preset pressures which can be customized by name and pressure. Most of the time when I fire up the app, the three fields appear blank. If I choose one while it's blank the system dumps all the air and goes to zero. If I choose one when the preset that I designed shows, it goes to the correct preset. This is glitchy. The system does not have a maintenance mode (like AirLift does) that will maintain the last setting. Once you close the app, it basically shuts off and remembers nothing. This makes it essentially a manual device. I set the pressure with the app, which is cumbersome. If there is a small leak or if the atmospheric pressure changes, up altitude, down altitude, trailer on, trailer off etc, I have to go back in and set the pressure again. It has no idea what I told it most recently. It seems like a simple computer chip or software adjustment would fix this.

I bought the "Pro" because I wanted to leave them at 0psi when I'm not towing. The Pro has a bumpstop inside to facilitate this. At 0 psi, my 2019 Ram 1500 Classic 4x2 is riding on the bumpstops. It is super uncomfortable. Maybe the 4x4 truck has more room in this area to allow some travel before hitting the stops, but mine is on them at ride height. At least that's what I'm feeling. Super bouncy and stiff even with no air in the bags. It seems to help a little to put a few psi in them, but that raises the back of the truck which isn't ideal. The build quality seems really good and they bolted in easily, FWIW. I was bombarded with advertising from PacBrake saying how much better the build quality is. Honestly I would rather have to replace parts now and then than be uncomfortable for 200k miles.

Shipping and delivery were just fine. The only problem is that the parts sent did not fit my vehicle And it cost me half as much to ship the parts back as it did to buy them in the first place and I still haven't received a refund....

Shipping good. Came with the wrong sized washers. Emailed customer service but no response. Air lines look a bit cheap. First impression not great. Hope they last…

Do not buy this it not work
