Estoy muy satisfecha con este producto. Desde que llegó, lo he usado casi todos los días y ha superado mis expectativas. La calidad es excelente, los materiales se sienten duraderos y el diseño es práctico.El envío fue rápido y el empaque venía en perfecto estado. Además, las instrucciones eran claras, por lo que no tuve problemas para usarlo desde el primer momento.

physical condition was bad

The instruction say to use the relay supplied with the shipment. After install of compressor and relay the unit would not shutdown when desired pressure reached. Unit is a little noisy but what good is that if it’s going to overheat and burn up due to defective shutoff sensor.

Works perfectly so far…. I would recommend to take pictures of an old compressor before disabling it… because my husband had really hard time to install the new compressor, until he figured it out that he was trying to install it upside down 😅😅😅….. after he tuned it the right way it literally took him 5 minutes to assemble it all ( I’ve helped to hold it in place 😅)…. I would really recommend this compressor…. It works…

I installed it myself, it’s working perfect. No loud sound as some reviews said. Works perfect. I forgot it was ever a problem. It’s been 4 months now.

It worked great on my car. Thank you.

Unit looks almost identical to factory, but the air inlet port is on the opposite side of the pump from the stock. It was not a huge deal, but it required me to remove the air inlet line from the mount it was on and move it to be able to hook up.The unit seems to work fine, but it is MUCH louder than the factory compressor. I could not hear the factory compressor when it kicked in if the vehicle was running. This replacement unit is very noticeable. As it should't kick in much it may be OK, but it does not convey the sense of luxury that you would expect from a Mercedes. I may decide to replace with a factory compressor at a later date and keep this for a spare. Time will tell.In all though, it seems to do what it is intended to do. Time will tell if it holds up OK. I suspect many of the people complaining that the pump didn't last long have other leaks in the system contributing to a premature failure. A new pump will mask the other leaks a system like this often has - so it is unfair to blame the pump unless you have ruled out air leaks in the rest of the system.UPDATE: Being disgusted with how loud the unit was and how often it ran I removed it to put the factory pump back in. I noticed there was a different height bracket on the OEM compressor, so I switched them and re-installed this Amazon unit. Low and behold it was no longer loud. I also discovered I had a few loose connections on the valve block. Once I tightened them all seemed to be working normally. I am leaving the item 4 stars as the air inlet port is on the wrong side, and I had to swap brackets with the factory compressor to eliminate the excessive noise - but knowing these things anyone should be able to make it work.

very very bad quality and lot of noisy,waste of time and money.
