Lot of 6 Owlet Smart Sock 3 accessories and device, includes: New Open box Smart Sock 3 Extension Pack (for 18 months - 5 years) includes 1 Right and 1 Left sock. Size 1 Right sock (under 12 lbs) never used Size 1 Left sock (under 12 lbs) lightly used Size 2 Left sock (12 - 30 lbs) lightly used Size 2 Right sock (12 - 30 lbs) used, light staining/wear We loved using the Owlet for our son and found it brought a lot of peace of mind. I am also including with the socks the actual owlet device (it is an Owlet Smart Sock 3) and charging dock. These were all purchased about four years ago. My memory is the device started having some issue and we stopped using it, but i honestly can't remember. It might very well be operation, fixable, or useless. I'm including it here bc it's doing me no good sitting in our closet and perhaps someone smart can figure it out.
