Just installed this 100 GPD RO membrane in my system and wow – the water tastes crisper than a freshly opened soda can! Removes impurities like a champ, though I did notice my TDS creep up slightly (from 2 to 4). Still way better than tap!

Pro tip: The housing can be tricky to align. Used the handle of my kid's plastic shovel to guide it in – worked like magic. Definitely an upgrade from my old 18 GPD membrane.

One weird thing? The product pics don't show it, but there's definitely no built-in check valve. Wouldn't risk using this with Watts Premier systems after reading those horror stories about backflow.

Delivery was faster than my Amazon Prime orders somehow. American-made quality shines through – even the packaging felt premium. My only gripe? Wish they included a little 'congrats on your new membrane' sticker or something.
