Hydroluxe Ultra-Luxury 2-in-1 Shower Combo

Hydroluxe Ultra-Luxury 2-in-1 Shower Combo

Bought one of these like 2, maybe 3 years ago. Still going strong, still looks like new. Surprised me because I have spent more on ‘quality’ name brands and ended up replacing them in less than a year.

What is the maximum flow rate. Is this a water saver?
