Works fantastic

The media could not be loaded. Junk quality. Pretty sure I had an issue with it (slow leak/slow rise) upon install, but kept thinking it was something else seeing that the part was new. Now it has gotten worse & finally narrowed it down to this block. It leaks from the back sideWhy did you pick this product vs others?:

The product worked as expected

The best

2007 Mercedes Benz S550 4matic. Just had a mechanic replace this since they were replacing a decent amount of the airmatic suspension already. I was having car too low and adjusting warnings pretty regularly and assumed it was from the only things I didn't replace, my front suspension. I have it sit for 4 hours and I come out to the front being too low and not willing to go up. It leaves me stuck 20 miles from anything with a wrench so I had to get it towed. I find out my suspension is fine but the back of the block is leaking from a seam in the plastic. The mechanic confirmed with a leak down test. Thing couldn't even last a year and even that would be too short of a lifespan. Poor craftsmanship with a return window of only one month. Don't waste your time with this one.

Great fit! Operates flawlessly!

It is working fine so far and I find no problems. It saved me a lot of money. I am pleased with this product

BEWARE ONLY 6-MONTHS WARRANTY. THIS IS A STUPID BASIC PART, THERE IS NO REASON IT SHOULDN'T HAVE A 12-MONTH + WARRANTY.Mine went 10 months and broke down in the lake of the Ozarks on Sunday 4th of July weekend. There were no rental places open and had to uber a hour away to Jeff city to get a rental.Repair took a week to get in / get parts / install. Luckily there was a reputable repair place that works on euros. If not, it would have been a flatbed to a dealership in Columbia 1.5 hours away. 5 days car rental, 5.25 hours down, 5.25 hours back. Food spoiled in coolers sitting in the heat for a week.I know that's not what I thought about when I purchased it, but whats the worst case scenario where you could be stuck?
