I purchased 2 sheets of Voodoo glass from Cointaker about 6 months ago, and I only have one regret - that I didn't do it sooner. Without being able to give your firsthand comparisons to other products, all I can see is Voodoo is crystal clear and I've nearly stuck my hand through it several times since thinking the glass was off. Voodoo is an excellent product from a great supplier.
Also, just to edify others (I'm sure you understand this from experience), these types of glasses do not eliminate reflection (that is a misnomer IMO). You still see lights off the backbox, ceiling lights, etc. and reflections still pass through up from the playfield. What they do is eliminate glare and haziness, which I guess has an element of "reflection" to it given that more light passes through the glass instead of bouncing off of it. When you look at a pin with standard glass next to one with Voodoo the standard glass looks dingy and hazy even when extremely clean (the haziness spreads the light throughout the glass giving in more glare/reflection) , whereas the Voodoo looks nearly invisible.
