WNL Products WLCRM CPR Compression Rate Wrist Monitor Practi-CRM | With Blue EVA Carrying Case, flexible one size wristband, tracks compression feedback for CPR practice

Great device works well

What I liked about this product is not very much and the reason why I do use it but you have to practically break your wrist doing the compressions before the green light comes on they need to adjust it a little and I understand it to inches depth compressions but you're practically breaking your wrist

Is a good example, because it takes several compressions until the light become green, like in the real life, if we stop compressions.

These are the bomb!! I wasn’t expecting much after another CPR instructor I know had told me they didn’t work well. They used the black style so I went with these. I’m not disappointed. They were great giving instant feedback to my class.

Works great.
