Not much to write about this. I purchased from Amazon after seeing on CNET (I think) as one of their recommended products. I think it was like $20 total.
I ordered the product and in about four days, it was delivered.
I opened the box. It had the oximeter, a small instruction booklet, a silicon cover, a lanyard, and two AAA batteries.
I put the batteries in the oximeter then the oximeter in the silicone cover. I attached the lanyard and turned on the oximeter. I put it on my finger and it gave me a readout that I can only assume was fairly accurate. I did it a few more times to see if there was any measurement variation. My pulse and oxiygen levels varied by 0 to 3 points but that was it. There were no extreme differences readings.
FINAL VERDICT: Although I've only tested it around ten times, it seems to be doing the required job. For the price of close $20 and being recommended by one of the review websites I 'trust', I'd say it was worth it for now as only time will tell for sure of it's longevity.
