Okay, so I got these tubing adapters hoping they'd be the magic solution to connect my Momcozy M5 with my Spectra pump. Spoiler alert: they weren't.

The packaging looked promising, but once I tried connecting them, the fit was just slightly too loose. Like that one friend who always says they'll show up on time but arrives 15 minutes late - close but not quite there. Total suction loss situation.

What's frustrating is the no-return policy if the seal is broken. I get it for hygiene reasons, but when the product doesn't work as advertised? That's $10 down the drain that could've gone toward coffee (we all know pumping parents need caffeine).

From other reviews I'm seeing, compatibility seems to be a gamble - some pumps work, others don't. Maybe double check your specific model before buying?

The concept is genius though! If they could just perfect the sizing for more models, this would be a game-changer for simplifying pumping setups.
