✅ Goes in the pool✅ Goes in the hot tub✅ Goes in the shower✅ Goes in the ocean✅ Goes in the sand✅ Gets sprayed with sunscreen✅ Gets sprayed with bug repellentStill works with no problem!I own an Apple watch also which ran me literally 6 times as much as this watch, and I think since I am a light smartwatch user I would be fine with just this one. It pairs for phone notifications, does heart rate and exercise tracking, and has alarms and timers.The best part has to be the battery life though. I recently spent a week at the beach, and rather than take my Apple watch and have to worry about it and charge it every night, I took this watch. I fully charged it before we left, left the charger at home, and when we got back it was still at 54%. It will literally hold charge for weeks.The UI is very, very responsive. Swiping around is nice and quick.I tested the heart rate monitor with one of those O2 sensor things you put on your finger and it was accurate.Now nothing is 100% perfect so here are some things I noticed.* Setup and some operations *requires* a phone. You cannot even set the time without a phone. This is a SMARTWATCH. If you're not going to at least pair it once with a phone this is not the watch for you. After the initial setup it functions independently, with only a couple of things like changing alarm times and getting the weather not working.* The features cannot be rearranged. Out of everything provided, I use the music controls the most to repeat and switch songs on my phone. This feature is the *last* one in the list, so if I ever leave it I have to swipe alllllll the way back.* The font used for notifications appears to not support emojis. If anyone sends you a smilely you're going to get a "?", then have to go to your phone to see it.All in all, it's an amazing product with a lot of value for the money. The watch firmware is upgradable, so if they fix any of the above issues, which I think is likely, it will be even better.

I really appreciate this watch and the features it has. First off, the smart watch was very easy to pair to my phone. I have an Android phone, and it only took a few minutes to pair the watch with my phone.First enable Bluetooth and find the device listed as "C20"Next, download the app that's shown in the QR code. Once you have the watch paired via Bluetooth to your smart phone and the app is downloaded, your watch ready to go, and should be syncing to your smart phone. The connection has been great thus far; it hasn't disconnected/lost connection to my phone.As someone who has suffers from pulmonary lung disease, I was very excited when I found out this smart watch has the capability to track my oxygen saturation, heart rate, and blood pressure. In addition, you don't have to do anything, the watch will automatically to measurements periodically throughout the day.It's helping me monitor and compare results over a few days. I suggest authorizing Google Fit so your hearth history is accessible when it. For me, it helps to have a history when I meet with my pulmonologist.The watch has great standby battery life, and it's light weight. After m three days it's only dipped minimally in available battery percentage. I highly recommend this!**Updated**So it's been several days now since I first posted the review and I am amazed how little the battery has drained. Needless to say this smartwatch has fantastic standby battery life; especially considering it's constantly looking for/measuring heart rate. As you can see from the photos the readings are very accurate. I own a pulse oximeter and a blood pressure monitor to keep my pulmonary hypertension in check. My resting heart rate is 95 bpm, which may seem high, but the reading is accurate and normal which makes this product more the reassuring.
