Has anyone had personal experience with "Vilagra"?

There is a drug produced at Centurion Laboratories (a division of Centurion Remedies Pvt) of Gorwa Baroda, India, called Vilagra (this is not a misspelling). Vilagra purports to be a generic version of Viagra, Sildenafil Citrate. Does anyone have first hand experience with using this drug or does anyone have information about Centurion Labs? I can purchase this medication, with a prescription, via a Canadian outlet, but I'd like to get information about it and the labs first. Please don't suggest that I google it, I already have. Thanks!
