There are a lot of double showerheads out there,but then you come across a Diamond glass double showerhead piece and right away you can see and feel the difference. For starters, the glass they use is just superb- it's heavy 7mm glass and they fire polish all of their pieces to make sure they have a brilliant shine to it. Their beakers are blown with a triangle shape that helps it sit sturdy and holds the right amount of water for a piece of its size. Then we come to the two matrix showerheads and they are the best selling percs that Diamond Glass makes and we can easily see why. Cut and blown with precision, they create some of the best filtration processes, and with two right above one another, you are definitely going to get that smooth hit you are looking for.
