Sounds like the Stratmosphere HX Hyperboost DV (undoubtedly the same thing) - look nice (had a pair on my car) - but the pistons need re-greasing from time to time, and the double O-rings need checking too. Piston DVs can get stuck if not maintained properly, and the O-rings can perish causing leaks.

Go for the 710Ns if on a budget, or (if you have the cash to splash on HX's) get the APR-R1's instead. IMHO etc...
