AuserOct 29, 2026 · Verified purchase ★★★☆☆

Refurb was fine - but don't trust fall detection - I was having some issues with balance and as a big Apple user I decided to get an Apple watch for fall detection just in case. Started with the SE3 and upgraded to this 7 in May 2026. I bought a refurb and it's worried it perfectly but for fall detection. Ironically it's alerted me when my cat knocked it onto the floor in the middle of the night (thankfully I canceled before an APB s sent) and even activated a couple of times when I was hammering something - not the type of activity I thought should set it off but at least it was confirmation it worked. Or so I thought. Then I had an actual fall, and since I have osteoporosis I could have broken a bone. Thankfully I was okay and the only thing damaged was my pride - then I realized my watch had not activated! I wear it on my right wrist and landed on my left forearm but I would expect a device to work regardless - who coordinates their landing based on where they wear their watch? Apple does have a disclaimer that it may not detect all falls but even so I think people expect better than this. And to top it off, I have found the feature sometimes turns itself off spontaneously. Insane! I'm going to have to get a pendant since I can't count on this. I recommend the watch SO LONG AS YOU ARE NOT COUNTING ON FALL DETECTION.

Excellent experience with this watch - Overall experience with this watch good features I recommend this product to everyone Only dislike about it is they don’t have the O2 or the sleep apnea feature on this watch

SallySOct 5, 2026 · Verified purchase ★★★☆☆

Nice watch - Love the watch but hate the fact that it doesn’t make it 24 hours on one full charge. That’s my biggest problem, otherwise it’s great.
