Hahaha same here.  I bought their 2" XJ budget boost (2" coil spacers, 1.5" shackles, and 1/2" lift blocks).  They had them on eBay but were out of stock.  After a very slow reply from them they said it was listed in error and it would take 2 weeks.  Two hours later they listed the same lift.
I'll give them credit where due, the shackles (and everything else) were excellent quality, and the coil spacers were a true 2" (many are only 1.5"-1.75").  
It took a long long time to get them, way past the two weeks.  I left a negative feedback for them and they left one for me advising sellers to block me and then saying I was "vulgar and adolescent in communication".  I absolutely was neither.  I left cordial messages for them and even made 2 phone calls wich were rudely responded to.
Both of the negatives were removed by mutual agreement, but I wished I had left it.  Check out their eBay feedback - there are many negatives, mostly for slow shipping, lack of communication, or not having the product in stock.  Apparentl;y their tactic is to leave a retaliatory feedback then ask for mediation.  They have had a LOT of feedback "mutually withdrawn."
How are their products?  I'd say excellent.  Their customer service absolutely sucks and they don't seem to give a damn.
