    Love my watch!

    • Verified PurchaserVerified Purchase

    I have been waiting for supporting cellular service for Apple watch. I love using and wearing this watch! The milanese loop band is expensive, but honestly, it's awesome. I love being able to slightly adjust it looser or tighter. I feel that it's very breathable and and sweat and water dry very quickly. I know some people say that dog fur or hair gets caught in the loops, but I haven't found that to be bothersome. I have a labrador retriever that sheds like crazy, and I find a single strand of fur in my band once every few days. I wear the band while working out, at work, or going out- it's very versatile. I like to swim laps, and the watch recognizes all the different strokes I do and automatically times each set. I didn't like at first that when you wear the watch, your message notifications doesn't make a sound on my phone, just the watch. But now I'm used to it, and I actually keep my watch on silent all day every day. I like the haptic vibrations on my wrist that notify me instead of an audible notification now. I use my watch every day, and am able to get 2 full days of wear before I need to charge again. The big downside is, using cellular/music on the watch, really drains the battery. I was at the gym, so I had an elliptical workout going, plus listening to Apple radio all on my watch. The battery died after just over an hour. Booooo. Overall though, I love love love my watch and would def recommend, esp the milanese loop.

    Great Weight

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite Plus MemberElite Plus Member

    So far so great! Outside of the LTE signal, the true differentiator for this watch is the OS. The much improved functionality, new UI and faster speed def make this a great watch. Sure, there are some improved specs but if I had to compare this to series 2, I wouldn't upgrade unless LTE was a necessity, which for me, it is. I've had no connection problems with AT&T as of yet. Once the watch recognizes that I'm not near my phone or a familiar wifi connection, it immediately goes to LTE. Battery life is ok. I can get through the day with modertate use but anything more will drain the battery much quicker. I love this particular model for two reasons. 1.) It has a nice weight to it and a premium feel which I love. 2.) It's very well polished space gray and although prone to smudges, it still maintains it's overall majestic appearance. I think anyone who buys this will be satisfied.

    Great update to the watch 1.0

    • Verified PurchaserVerified Purchase
    • My Best Buy® MemberMember

    Got the series 3 sport as a gift, and fortuitously returned it at the same time this went on sale, and was able to snatch it up. Had some doubts, as thought I might want to hold out for the series 4; I'm glad I didn't. The 3 looks great, functions perfectly (especially with the new OS update) and is currently much more affordable and obtainable than the 4. It's perfect for runs, the activity monitor seems more sensitive than my old 1.0 (logging more calories without any additional effort), and the steel case is seemingly more scratch resistant than the case on my steel 1.0. Battery life is amazing - full day, and still have 60% charge. Never been so happy with an apple purchase. If deciding between 3 and 4, don't question it, this is worth it.

    First Apple Watch... on purpose.

    • My Best Buy® Elite Plus MemberElite Plus Member

    I have been waiting for this Watch to debut since the first watch. The reason I have been holding back on previous watches is due to those watches needing to be tethered. I love the, “007” aspect of this Watch. No need for my phone to be near by anymore. Coverage has been awesome so far with Verizon. The reason I am giving it a 4 Star is due to the battery. Apple has been getting pretty good at their batteries for the phones. For that reason alone, I would think that the battery life would be plentiful with the 3rd Watch. If it were possible to give a 4.5 star, I would have.

    Love this watch!

    • My Best Buy® Elite MemberElite Member

    I love the upgrades on this watch! Increased RAM, the cellular connectivity and the fact that I can talk to Siri from my watch has been great! There is a new barometric altimeter on this watch that now counts how many flights of stairs I've climbed. The signal strength on the cellular connectivity of the watch has been great so far. Pros: Improved performance Great battery life when connected to a phone Wonderful new fitness features Siri works great! Cons: Apple Music streaming is not ready yet Battery life on LTE could be better

    Nice time piece

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    Was looking to get a deal on an apple watch since I had reward points for it. I researched the watch quite a bit and compared to others on the market it was the better choice. I personalyl prefer the round bezel but I got used to the square apple watch one. I like the activity trackers quite a bit although i'm not sure they're 100% accurate as I sometimes feel I "accomplish goals" simply by standing someplace. Other than that the screen is beautiful. Need to recharge once every 2 days approximately.

    Happy Series 3 can go in the pool

    • Verified PurchaserVerified Purchase
    • My Best Buy® Elite MemberElite Member

    I had the first version of the Apple Watch, but had to be very carful not to get it wet - although one clerk did say it could be worn in the shower. I am very happy with my new Series 3 Apple watch that I don't have to worry about taking it off at the pool and leaving it unattended. It took some learning about clicking on the the water dot and rotating the bezel to push out any water. I also wasn't sure if I would like the Milanese Loop, but I really like it and it is easy to use.
