We recently had to return a gorgeous Alfi square shower head ( http://www.wayfair.com/Alfi-Brand-8-Square-LED-Rain-Shower-Head-LED5001-NBT1000.html ) as we did not have enough water pressure to make the lights work. This lights up very well with our low water pressure. Only downside is all the plastic components. The Alfi was constructed entirely of metal and was so sturdy.

Pros: lights up nicely and has good pressure
Cons: it's plastic
