Not a bad bar by any means. Personally, though, I'd prefer the Feniex Cannon interior bar - same price, lots more LEDs per head, and more patterns I believe. Plus TDs can be had in any position.
it's an okay ILB. For the $500 price range it's solid & decently-bright. They're a smaller company and I think they're slower to advance with newer technologies than the competitors (they were still doing a lot of Gen I 5 mm products for a long time after Gen III was around), but they're reliable. However, if you can afford it, I prefer the Sound Off & Federal Signal ILBs (although they start around the $700-800 range and are usually above most ppls' POV budgets).
