Design & Build Quality
The Express Water RO5DX exhibits a rugged build with visible robustness in its metal fittings and thick tubing. After dropping its component accidentally during unboxing, I noticed a minor scuff that didn’t compromise function.

During my testing, the plastic housing presented minor scratches when sliding it into place, which speaks to its lightweight, albeit less durable, construction.
