The sock itself is pretty great but the sock with video has a ton of false alarms and unhappy customers. Owslet customer service is pretty lousy when trying to return your product and most places have a return policy of you open it and it's yours when it comes to the product.
That being said, I think unless you have a preemie or a medical reason for it you should save your money.

Was 100% worth it for us. Never had a false alarm and gave me so much peace of mind.
