These are the familiar Ansmann threaded shocks, just with a new name and a black paintjob. As such, they have the same pros and cons as the Ansmanns, namely well-machined alloy parts coupled with poor assembly and shaft seals that are prone to leaking. However they are very affordable, so if you don't mind taking them apart to remove the moulding flash from the pistons, and rebuilding them with good-quality o-rings on the shafts, they represent good value.

I bought these to use as a 5th / 3rd shock mod on my Tamiya Lunch Box. The one I used works really well and I have the other as a spare.
