Perfect Product as per Specs. I purchased 2 times before never disappointed me. I love this product.
Order received. Pulse Oximeters are excellent, very useful thing at present, the data show correctly (checked at work), it's about medicine. I especially want to note the seller, very professional service, helps in choosing the device. I definitely advise the goods and the seller. I will contact the store again.
Works! There is no possibility to check the indicators. Probably order more parents. The seller is decent! Recommend!
