very good

Poor quality. Pump stop working in around 9 months. Car is barley used, but still this pump managed to fail.

Compressor works well it does its job. Only downfall is it’s super loud. Not quite like the oem. Makes heads turn when filling.

Used on a 2016 gl450- 3 months in still works as it should- great part and a small fraction of Mercedes cost

I replaced OEM air suspension compressor pump on my GLS450 for this Amazon YDMON part, the noise coming from Pump is extremely that you can feel it inside cabin. Absolutely a No-Go.

good product willing to buy again..

Fixed up the escalade this pump fit right in and works perfectly.

From what I can see tell this air suspension compressor pump is well made with quality parts. It functions well and inflates properly. I do feel like the noise level is louder than my old one.
