I always use Delta. I have used other, Why Delta? First , they have a universal shower valve body. The body that I installed to go with this also had shut off on the body, so if you needed to change the cartridge , you wouldn't need to shut the water off in the house, nice feature. Also, you can get new cartridges just about anywhere.
Now to the item listed, It came in the allotted time, packed very well. The finish is very good, fit the valve body perfectly and works very well. The installation was very simple and really didn't take a long time.
