AmbiTech High Accuracy Fingertip Pulse Oximeter, SpO2, Perfusion Index with OLED Display

Bought Ambitech High Accuracy Oximeter 3 days back and from the day I bought this product, it's not showing the accurate result and within seconds it dips from 98 to 60s . Tried this for 2 days but it's the same. Hence trying to reach the manufacturer to return or replace but not finding the option.

Received the product before date than said date. Packing is good. Separate pouch is given for the Oximeter. Highly durable Duracell batteries are also provided along with the Oximeter. Liked the product very much.

Accuracy is very poor and misleading, multiple consecutive readings have huge differences

Fake product..Sent old , full of scratches, not working up to mark..And no returns/replacement provided..Cheated.

Very nice product

Please don't buy this product it's totally WORTHLESS and waste of money. It doesn't work properly at all.

Its defective and broken please refund my payment

Good product and value for its money.
