So the idea has been pondered and discussed many times on here, myself included. Nearly all people even thinking about it though, have ended up going with OE ones the cost notwithstanding.
You can do a search but here's at least one thread talking about them:
In this thread you'll find (about halfway down the first page) a guy that
did use the China/aftermarket shocks:
A few weeks ago I had to change one of my rear brake calipers as it had seized up. 3 years after the other side had seized up. Anyway, while the wheel was off i noticed some dust build up on one of the shocks. Now I know the workshop manual says that a light misting is no reason to change it and...

Not the thread starter but a different guy that chimed in. His use of the aftermarket dampers is kind of overshadowed by his rather ingenious jerryrigging of the rear cap in order to not have to replace it (they are extremely expensive these days), but you'll see he did mentioning using the aftermarket shocks and not really having any immediate issues. However he didn't really know what good/working OE dampers should feel like so not much in the way of comparison there.
Also, he only made the few posts that he did at the time (over a year ago now) and never returned, so no word on how his car/shocks are doing a year later. Apart from that, the rest of us that have replaced dampers (either singular, in pairs, or full refreshes as I and a couple others have done)
on here...we've all used OE parts.
There's a lot of people that have bought these things to be sure, the problem is you're not really seeing much feedback on the intarweb about them as whoever has been buying them are not the type to post on here or other sites it would seem. It's also possible a lot of them are purchased/used by used car dealers just trying to get a car up to spec using cheap(er) parts like this to get the job done, esp. given the cost of the OE ones which is all very high these days.
So you're more or less the metaphorical guinea pig here unfortunately. One suggestion I have is you might want to go with ones from a more established and standing "brand", well as far as one can go in that dimension when talking about parts like these. I've often mentioned and seen mentioned for other magride cars (like GMs) one company called Aerosus. They have a website (
Air Suspension Parts and Kits | Aerosus for UK) and sell on eBay, offer a warranty, and all that stuff. Now how good the support or warranty actually is I can't comment on that, but they at least
say they offer 30-day satisfaction guarantee and 2yr warranty. So at least
in theory, they should be a safer bet than totally unknown/fly-by-night rando sellers on eBay, Amazon, etc.
This is not a testimonial of any sort for this company as I've never done business but when I
was considering buying aftermarkets, that was the company/brand I was going to go with. "On paper" they seem a bit more safe/sure than others...at least from what I saw at the time.
