On this type of thing specifically.. if you have a significant other that has a lot of hair to deal with, ask them first. 1.5gpm of flow over 12 square inches isn't a lot of pressure. It can take a while to get certain products out of long hair.

I don't know about that particular model and i don't see anything about int he q/a section... but if you don't care about the environment or your water bill, many shower heads have removable/drillable regulators that will help with the flow issues.

If you're not going for a wand, don't sleep on simple but effective: https://www.amazon.com/gp/product/B006FYAASC/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1
