This is a very poorly made very inaccurate device. The batteries will not stay in and the battery cover will not clip shut. The readings are very inaccurate - I am much better off taking my own pulse. Brought this device to my doctor"s office to check accuracy against their equipment and it consistently displayed values that were not even close to correct. You should be ashamed to sell such a product to seniors who depend on these devices. Now my resources to purchase another are gone and I reallly need one as I suffer from atrial fibrillation. Has you company even heard of quality control?

My PO60 works exactly as advertised, simply install 2 batteries and turn it on. Syncing with my phone is seamless, so simple even a Caveman could use it!

I was very disappointed when I opened the item. I put the batteries inside and it wouldn't snap together, I had to tape it shut. So disappointed especially since I really needed it. Not the quality purchase that I am use to from this company, I felt like I ordered it from Wish.com.

I just purchased the pulse ox monitor PO60. It's rating, Beurer's reputation and my experience with other products they make made the purchase a simple decision.
I already have three Beurer products that are bluetooth and this pulse ox monitor rounds out the set. The BF70 scale, BF67 blood pressure cuff and the FT95 thermometer.
All three give consistent, accurate readings that download to my phones Health Coach app. I was using pen and paper to write down readings on sticky-notes which gave a good visual for tracking progress but it became cluttered and disorganized. Now, readings are taken and transferred to the phone for storage, seamlessly. I can trend at a glance and keep the information organized and securely out of sight on the phone.
If Beurer only offered a bluetooth step counter and a sleep monitor to go with the app (it currently supports them), I'd pick them up also.
Keep expanding the product line Beurer. Good job!

Nice product and quality
