haven't had any issue other than lanyard broke after 1 wk. not super fast reading, but not overly slow.

Good ig. It's helpful ig. 4 stars ig.

Love the ease of use and portability of the product, readings appear to be a few points lower than my hospital machine though, still nice to have

Very easy to operate and light.

Great size, easy to use

Does exactly what is supposed to do. Simple to use and easy to read. Pulse is right on, will compare OX levels to my doctors device on next visit. Consistent results after many tests. Great value.

A little slow to acquire and display data, but OLED Display is spectacular.

It works as described. I like to have it in case I need to test it.

Works well. Easy to read.

Good price for this product.
