      5.0 out of 5 stars Love my Apple Watch series 9

      In my experience, Apple never fails to deliver a quality product. This is my first ever Apple Watch. I got the series , 9, 41 mm. I bought a new one instead of refurbished because I wanted to have all of the guarantees of a new watch. Amazon offered some great options and prices and I ended up getting mine for about $50 less than if I had bought it from the Apple Store. I called Apple and asked them about buying an Apple Watch from Amazon and they said they support all of the retailers who sell their products, but could not guarantee it if it was refurbished so that was why I decided to go ahead and buy brand new. I’m still learning a lot of the details of the watch, but it is so nice. It mimics my phone perfectly plus add some fun Clock faces and additional features for working out and health benefits. I love the functions and the size is just right. You have options to make it very bright or keep it dim. So far I just charge it in the evening. I haven’t had any problem with it losing its charge last night when I charged it. It still has 67%.
      I’ve always worn a Fitbit and they offer good products as well, but the iPhone just does so much more! I love it!!

      5.0 out of 5 stars The Perfect Mother's Day Gift – Stylish, Functional, and Simply Amazing!

      Color: Pink Aluminum Case with Light Pink Sport LoopSize: 41mm CaseStyle: One Size - fits 130–200mm wristsVerified Purchase
      I recently upgraded to the Apple Watch Series 9 [GPS 41mm], and I couldn't be more impressed! From its sleek design to its incredible functionality, this smartwatch has quickly become an essential part of my daily routine.

      First off, let's talk about style. The pink aluminum case with the light pink sport band looks absolutely stunning on my wrist. It's stylish enough to wear with any outfit, whether I'm hitting the gym or heading to a business meeting. Plus, the lightweight design makes it comfortable to wear all day long.

      But it's not just about looks – this watch is packed with features that make my life so much easier. The GPS functionality allows me to track my runs and hikes with pinpoint accuracy, while the heart rate monitor helps me keep tabs on my health and fitness goals. I love being able to receive notifications right on my wrist, so I never miss an important call or message, even when my phone is out of reach.

      The battery life is impressive too. I can go a full day on a single charge with plenty of juice to spare, even with constant use. And when it does need to be charged, the magnetic charging cable makes it a breeze to power up.

      As Mother's Day approaches, I can't help but think what a perfect gift the Apple Watch Series 9 would make for any mom. It's not just a stylish accessory – it's a practical tool that can help her stay organized, motivated, and connected.

Whether I'm staying on top of my fitness goals, staying connected with friends and family, or simply checking the time, this smartwatch does it all – and it looks good doing it. If you're in the market for a new smartwatch, look no further than the Apple Watch Series 9. It's stylish, functional, and simply amazing – the perfect Mother's Day gift!

      The media could not be loaded.
      This is a nice, sleek watch. It has been a game changer for my exercise routine and essential for my overall health. And as someone with ADHD, this has been an amazing tool for locating my phone in a pinch.

      I have to take a lot of medication in a day. I put the information in the health app and set reminders, the watch reminds me until I long the medication. It’s been very helpful, and provides an easy way to record the time my meds were taken. I consistently have panic attacks, and my watch will notify me when my heart rate spikes, giving me enough time to relocate and try to ground myself. The breathe app is also a great grounding tool for me, the haptic feedback is a great thing to focus on when everything else around me gets hard to process. Furthermore, it has made it easier to sleep! I have never completed a 5 min breathing exercise in bed, I always fall asleep before it is done. I just close my eyes and match my breathing with the vibrations, it eases the anxiety and gives my brain something to focus on when winding down. Speaking of the haptic feedback, that combined with the amazing sound coming from this watch has broken my habit of snoozing the alarm and falling back asleep. This watch also tracks my sleep, so I can get an idea of how long I sleep each night!

      For exercise, it has been nice tracking my steps. I had no idea that I walked up and down 27-30 flights of stairs at work! I knew I moved around a lot, but not that much. It serves as good motivation for recording my exercises at the gym. I now log everything and can create a nicer workout schedule.

      The battery life is great, and it takes maybe 45 mins to charge. I keep it on when I’m sleeping and charge it when I’m showering before work. It is water resistant, but I don’t think I’ll ever be comfortable with wearing a watch in the shower. So far there have been no scratches on the display, and I don’t have a screen protector on it. The only thing I don’t like is the wristband. I think it induces sweat that ultimately irritates my skin, so I habitually wipe it down with an alcohol pad. I’m on the lookout for a professional looking band that has nice airflow.

      If you own an iPhone and want the best smartwatch experience, the Series 9 (GPS, 45mm) is an excellent pick. The performance, display, and fitness features are top-tier, but battery life could be better. If you already have a Series 8, the upgrade might not feel massive, but if you’re coming from an older model, it’s definitely worth it.
