American Standard 4188A.155.020 Cadet Pro 1.28 GPF Tank with Aquaguard Liner and Right Side Trip Lever, White

Replaced my old (~30+ years) Grohe single-handle, spray pullout with this new one. Installation was relatively simple and faucet works smoothly. When it is in spray mode, the water flow is quite strong, but in stream mode, the small stream seems to flow much slower than the spray. It is still adequate, but hard to understand why. The overall build and inner works are high quality as you would expect from Grohe, but the pull out handle is plastic. It seems substantial enough, but wonder why Grohe moved to plastic for this part? Overall very satisfied with this good looking and economical faucet.
