What do I know?
I know that the whine that is associated with them is not "normal", like everyone says. Its from them being hundreds of dollars pieces of shit and piss poor quality.

Here is a thumbnail image (clickable) of an online buddy's unit after a few months of casual, non-aggressive driving:


After all was said and done, the only person who took responsibility (after MUCH debate) was Perpetual Concepts, the store that sold it to him. SRR claimed no responsibility and basically said it was not their problem. Not once did they mention replacing a part that is obviously defective, and of poor construction. They even claimed fault of fluids....like there is some magical mft that srr is the only owner of. Plus, the fact that they speak very little and broken english, doesnt help the fact.
If youre going to sell something world wide, you need reps who are able to speak AT LEAST english as a second language (and well).
