    Good product but a bit pricey

    It’s a good product, but more expensive compared to other oximeters in the current market.

    Pulse Oximeter

    Very easy to use (although needed help from a medical friend to make sense of the readings). Item was ordered and received within a matter of days. Great service.

    Excellent Oximeter

    Received Oximeter very quickly, and since this was in the middle of covid, that was really important for me. Works great, have never doubted that the readings were correct. Have changed battery already, but considering I was using it multiple times a day at first, not surprising that the battery ran down. Very happy with this purchase and St Lukes Life Pharmacy service.

    Useful equipment

    The oximeter gives a great sense of security during covid and influenza season by providing reassurance that the oxygen level is satisfactory.
