  1. Usually, chinese watches dont have strong vibration, which makes you miss some notifications. Does this one have strong vibration?

  2. Nice review, looks like the same size of an Apple Watch, does it has any GPS connectivity ? Would it work if you are in the middle of nowhere and need gps or signal your position ? Thanks

  3. Thanks for the recommendation. I have a Applewatch that is failing and Iโ€™m looking for something different. Iโ€™m not sure how this will work on my 7โ€ wrist (all a lift are fountain pens). Enjoy the tip and get something on Fort Street in Victoria.

  4. They are looking nice. The problem is all Chinese smart watches measure heart rate on banana tomatoes and many other things. Can you check if this one does?

  5. Bought one. Thanks for the recommendation! Really enjoyed the part where the knife didn't leave any marks.

  6. I've been enjoying the Tank X2 Ultra that you reviewed some time back. I would like to be able to replace the band with a metal mesh or cloth band though.

  7. I did buy one.

    It looks and feels nice.

    But it's software is buggy. Mine crashes a lot and shut down random.

    After restart everything is back to factory settings, data is lost, settings are all back to factory.

    Don't think to get customer service, all you is get is an auto reply over and over.

    Just to be informed!!!

  8. Cool review. Waiting 2 days to get paid so i can get me this watch.
    A lot of others to choose from but its the shape that i like,don't really like the rounded ones so this seems like a good choice.

  9. Do you have to buy/pay membership to use. Way overkill for what I need (just distance in mile walked), any further advise. I do follow you for fp too.

  10. I would like to recommend Amazfit!

    Lots of models, I personally have the Amazfit Bip 6 (excuse the pun but amazed with its battery life, I wear it 6 days a week while out and take it off for the night, and it hits 20% charge after about 4 weeks).

  11. What is KOSPET? Seems to be a sort of Chinese holding company. TBH, I get the same functionality with a 4th-gen OURA ring and my Google Pixel 8a

  12. Tank could refer to the famous Cartier Tank watch, which has a rectangular case.

  13. Wonderes what would happen if you chose mountaineering for the way to get to Ikea. ๐Ÿค”๐Ÿค”

  14. Great off-brand review! Quick question: have you tried the walkie-talkie mode between your M4 and M2 to test if it actually works? Or is it just introduced in M4, and not present in M2.

    Thank you, and have a nice day!

  15. Thanks for the review. Iโ€™ve used an Apple Watch 8 for over a couple years. I get frustrated with it, but it does work seamlessly with my iphone and the health/sleep functions.

  16. Hmm ๐Ÿ˜Ž I'm not much of a Watch/computer/Dick Tracy watch guy. Solar Quartz movement are pretty accurate , and once charged they will run for months. BUT WOW! I can see the draw of a watch such as yours! So many (and I'm amazed at how many) features! Very Cool ๐Ÿ˜Ž๐Ÿ˜Ž๐Ÿ˜Ž

  17. Even reduced from 200 to 180 dollars is a no thanks from me. Almost half my pension here in Europe. You Americans who earn 200 dollars in a day you can have it.

  18. Nearly tempts me to switch from Apple Watch to this, though I wonder why they have removed the blood pressure function. Also they miss fall detection. So maybe Iโ€™ll have to wait until they release a new model to you ๐Ÿ™‚
