Press your lips together to stop the air, then release. No vocal cord vibration.

Americans pronounce product as PRAH-duhkt (/ˈprɑdəkt/). In "product", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. This is called the Flap T, and it's one of the defining features of casual American English. So instead of PRAH·tuhkt, you get PRAH·duhkt. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "Let me walk you through the key features of our product" or "The gross domestic product grew at an annual rate of three percent" — more examples below.

The textbook way isn't wrong — it's just not how anyone actually says it.
In "product", the "t" between vowels sounds like a quick "d" — the tongue briefly taps the ridge behind the upper teeth. /t/ or /d/ becomes a quick tap [ɾ] — sounds like a soft D. The tongue briefly taps the ridge behind the upper teeth.
In "product", the "t" is not released — the articulators get into position but hold without the burst of air. Air stops but there's no release burst — the articulators hold position.
Stress falls on the first syllable, not the others. Stretch PRAH — keep everything else short and quick.
Don't pronounce the first syllable too fully. The unstressed syllable reduces to a schwa — the lazy "uh" sound — in casual speech.
