Out of the box:
- Packaging appears sufficient. Unit come with 2 AAA batteries (non-alkaline?).
- Carrying case is included with velcro closure which is nice. A lanyard is also included which was immediately upcycled into a cat toy.
- The display is in the opposite orientation of the person using it (up-side-down) which makes it a little difficult for self-administered testing as you are to remain still for optimum test results.
*NOTE: I recommend disposing of the supplied batteries as they do not appear to be alkaline or better. These batteries are known for low expected battery life cycle and leaking over time and especially with infrequent use. Battery acid can significantly harm electronic components and insulation resulting in premature circuit failure.
Operation:
- Simple and straight forward, put finger in and go.
- Unit will self-power down after a few idle seconds.
Accuracy:
- Appears to function as advertised. I am going to compare with medical grade equipment and update my review accordingly.
UPDATE: compared to hospital equipment, values were within about 1% during 8 minute comparison. I did note that the refresh rate in this unit was actually faster than the professional unit...impressed!
Long Term Reliability:
- Initial impression based on the visible components and attributes used:
- Cover appears to be snap-fit or perhaps sonic welded.
- Wires used to connect bottom sensor to logic board in top half are wrapped in tubing and are sightly exposed in the rear of the unit. It is unclear if there is any strain relief on these wires. There is a slight risk of wire continuity failure due to flexure of wires during normal operation (open/ close finger clamp).
- Both labeling and device serial number are laser etched. This is a pricey process when compared to standard poly labels and is indicative of an advanced manufacturing facility.
- Device is made in China by Contec, an FDA registered company (Reg# 3006979678) whom also make EKG machines and other sophisticated medical devices.
Overall Risk for LTR= Low for average consumer usage, LOW-MEDIUM for regular/ vigorous use due to possible wire flexure failure.
- Demonstrated LTR is pending use.
Overall Verdict:
- Good for the average Joe/ Jane and can't beat the price.
