I’ve been dealing with some cardiology issues for the last several years; therefore, I have several of these pulse oximeters (from different manufacturers). I think it’s also a good idea to keep an extra one in your car as well.
I recently received the Zacurate Finger Pulse Oximeter (model 430/DL). It is well made, and appears to be accurate (I measured against my other pulse oximeters). What’s also nice is that the compartment where you insert your finger is very comfortable (more so than other brands). Also, a good value as the price includes a rubber cover case, a lanyard, as well as a sturdy nylon travel case.
However, I’m only able to give the product 4 stars overall because of two issues ; while you can easily change the display format of your pulse and oxygen levels into six different formats, the unit doesn’t “memorize” the last format display you set, therefore, when you use it again, you have to toggle back to your display preference (if it happens to not be the default display mode). And second, the unit, as advertised on the manufacturer’s website, state’s that it is accurate to within +/- 1%, however, the literature received with the product still states it is accurate to within +/- 2%. I spoke with the seller on this, and they stated they are in the process of updating the language in their literature but that the product is accurate to within +/- 1%. With this said, all in all, I recommend the product with 4 stars.
