Needed a pulse ox to monitor 2 asthmatics & a husband that snores & has bad sleep apnea. Wanted a cheaper one but knew that I needed one that had an alarm AND recorded, & the little "All-in-one" finger gizmos would be a waste of the money. This worked right out of the box, is light, stays on the finger all night without too tight but not fall off, AND the software was very easy and very professional reports. It has helped us battle the insurance company to provide my husband with a CPAP machine. If you want one for home use--this is it. If it is for sports you'll need a pocket & it does have the wire attached. Came fast & if this is the one don't waste your time trying to find it on other sites--I spent hours to save money & ended up this was the best place!
