Open-Box | Rechargeable | Handheld Oximeter PC-66L

Works well. Had a question about connecting the finger probe so I called customer support, no answer, so left name and phone number but never received a call back. Seems like customer service might be kind of weak.

Great product. I've gotten 2 of my co-workers interested in purchasing it. I don't know if they have gone through with it

Love this monitor and the company honored their warranty when we had an issue with its cord 6 months later.
