Not trying to knock Nazar's wares... just sharing with you that the Stargate reputation has been very spotty.
There are Stargates.... Stargate Knock-offs and knock-offs of knock-offs.......
The most reported flaw was a rusted out downstem where it screws in and seperation of the acrylic on the vase. Rust outs were complained about the most... these were reported around 3 months to 1 year of ownership.
I never went for one myself..... so no first hand problems.
