i'd purchased a unit from them too, was posted on ----. my unit is dual 250w mh and dual vho's.
shipping is prompt, but the ballast was damaged when it arrive. emailed them with picture of damage, a person name Kim sent another ballast right away. She even paid for shipping for the damaged ballast. I think UPS dropped the ballast during shipping... all in all, they replaced it without questioning.
