anybody buy/try these heads?

From what I have found in the web, it looks to be another high volume head shop, and so the quality would be a crapshoot. As for the castings...... I have to worry about the old adage of 'you get what you pay for'. And what does this mean? "much thicker in all the critical areas" LOL
yeah, by all they sell, it's pretty obvious there is a lot of heads being moved through there shop. Yeah, a little more clarification would be great on where "all the critical areas" are. Leaves one to assume where the originals crack. But who knows....
