Firstly, the communication with the team was on point! Package arrived fast and secured nicely. Once you receive it, charge it for a few hours and get the smartphone app! It is free to download and use (huge bonus for me), fast to do the setup and allow the sharing toggles. After that, you're good to go! Facebook notifications, emails, messages, phone calls (audio quality is close to my phone speaker), waterproof (tested in the shower), health features (blood pressure, oxygen and a few others), bright display, long battery life and probably the most important, so tough, scratch proof and unbreakable. F*** the conventional brands and their overpriced devices!

I knew what I was buying as my friend has one too. Cannot be happier with it, delivery time was under one week, all the functions are accurate and the battery life is impressive. Keep up the good work North511

I love how it looks and feels but most importantly it brings a lot! All the features you could think of (and some I don;t really use - but they are there). So many watch faces, scratch resistant, waterproof, health information, sport activity tracker, step counter, etc.

I came to get one for my son and I decided to leave a short review. The battery life is up to 25 days (for me). All the apps are working beautifully, the data is shared on the smartphone, sleep tracker, sedentary reminder, alarm, heart rate, oxygen level, calendar, messages, twitter notifications, calls, emails, everything on your wrist!

J'ai vu une super annonce sur Facebook et je voulais l'essayer. L'expédition a été super rapide vers Marseille et l'équipe de support était très gentille. La qualité de fabrication de l'appareil est excellente et je n'ai aucune plainte.

Die Smartwatch kam sehr schnell an. Es stehen viele Sprachen zur Auswahl, die Funktionen sind fantastisch und die Telefon-App ist intuitiv und einfach zu bedienen.

Superb quality! I just changed the band to one that I bought in my local watch store. Apparently it's highly customisable (that's what the technician said about the smartwatch) so you can get a coloured band if you feel like making it a bit more sporty.

My friend is using an apple smartwatch that has almost the same built quality as this one. Image is the same, features are similar but on mine the battery life is 2-3 weeks. Just the first few days after receiving it I had to recharge it after 11 days but I had to check everything so it's justifying that the battery drained faster than normal. No complains, customer support was helpful and fast via email (not sure if they also have over the phone customer service).

I was sceptical thinking that it won't be bright enough in the sunlight as I work as a contractor. I had a garmin before and that was the main issue but not with the invictus north511. Even in really sunny days the data is easy readable and this is for me a big plus. Everything else works more than fine and the battery lasts forever. Thank you

I didn't expect this quality for an under $100 smartwatch. I wear it everyday with no problems, no discomfort due to the square like shape and the functions are really helpful. You do have to connect it to your smartphone for data display but the setup is fast and easy. Apple, Samsung and other brands are overpriced

I was looking for a capable smartwatch and I found this. I was happy when reading the description but when it came I realised it has more features. So useful and easy to understand. Fast charger is included in the box and also a tool to modify the strap length!

Intuitive menu and it has all the functions anyone can need. Probably if you work in special forces you will need something with a little more capabilities but for 99.99% of people, this does the job more than fine. Arrived in little over 12 days so this can be improved (4 stars).

Best smartwatch. Used it for over 5 months and battery still lasts like after the first charge.

Lo compré por las funciones de salud, pero ahora también uso la notificación, un contador de pasos (realmente útil), un monitor de sueño y un recordatorio de sedentarismo. Lo recomiendo altamente!

Really well packed, the Invictus arrived in great condition in about 8 days (in Denmark). Right out of the box, the quality is impressive and once you pair it with your smartphone you get so many features. I also tested the water resistance as I took it in the swimming pool - works perfectly fine after 30 minutes in water. The longest time I used it without charging was 23 days so more than they advertise and in the app there are hundreds of watch faces.
