This is the second frameless shower I have installed and this is by far an inferior product to Dreamline shower I installed.
First the materials are of less quality. The handle looks and feels weak. The brackets are one-sided which is insufficient unless you bolt it to the wall. The anchors provided should be replaced as they are insufficient to hold the weight. The use of plastic trim throughout the design is cheap looking and because it is integral to the design (even the stationary glass component), it means likely early failure for those components and rework later on. The components do not hold snugly and the use of single bolt points contribute to what seems like a wobbly design.
The worst part of the installation experience was when I was holding the shower door for installation it shattered. I'm not an expert on tempered glass but I have serious concerns with a product that breaks when being held in the air (not in contact with any other materials). I did call product support and they were willing to ship me a new door for about 2/3rds of the price of the original purchase. I opted to use a local tempered glass manufacturer who could provide a better price, better looking handle, and all for less.
I've read good things about Vigo products but I would stay clear of the frameless doors. I'm still nursing cuts and cleaning up glass from my installation.
