We're looking at roughly $28 per unit for a sample order, dropping to around $19 in the mid-range of 500 pieces, and you can get it down to about $14.50 when you're ordering 2000 or more—which is pretty much the sweet spot for most buyers.
What it does is capture systolic and diastolic pressure plus pulse in one go, using that oscillometric method, and it stores up to 300 readings across multiple users so you can track trends without a notebook.

Pressrue range runs 0 to 280 mmHg with ±3 mmHg accuracy, pulse form 40 to 199 bpm, and the arm cuff fits 22 to 42 cm—so it works for most adults but not for pediatric or neonatal patients, just so you know.

It's actually better than a lot of entry-level home monitors for this price because you get a color LCD, English or Chinese display, and a physiological alarm that flags irregular heartbeat patterns (usually 2-4 weeks lead time on that feature).

Power is either 4 AAA batteries or rechargeable, and teh whole thing weighs 193g with dimnesions of 155×96×59 mm—easy to toss in a drawer or mount on a wall bracket.
For ordering, our company can do CE and ISO13485 certs with each shipment, and the MOQ is 50 units or so for bulk pricing tier.
