I love my Samsung gear watch but when my dog chewed up the band I thought it might be done for. However, the new band was easily installed and more attractive than the original.

The watch sometimes looses it's connection to my phone. Once that happens you have to play with it to get it to connect again. The office in which I work no longer allows us to bring in our cell phones (anything with a camera actually) in the department (we have a locker room, so high school). One of my parents is sick, I need to be able to receive my notices in case of emergencies, therefore the watch. but if it does not serve it's purpose I will be replacing it.

I did like the watch initially , but after a week or too the lense became lose and I put a little glue and it ruined the watch. I ended it buying another because I did really like it but again the lense came off. I love the watch but it needs to made more secure.

The FIRST band lasted about a week.  I loved the concept I hate the standard watchbands that stick out and get stuck on everything.  I tried changing out the band back to the original one I received with the watch and it broke! I had to pry the metal piece from the watch...I was sad!!

***UPDATE***the seller reached out to me after my review.  I was given a FREE replacement; which arrived in a matter of days; the band was attached to my Gear S2 and it has worked perfectly ever since!!  I'm a happy camper with the both the customer service and the durability of the product!!  Thanks for making it right!!

I fell in love with this watch but I am disappointed that it stop ticking. I am not sure if it is a battery problem but I think in future reference things like this should be avoided especially  product like that

Once I attached it to my samsung watch the band wouldn't come off--so I guess I'm keeping it forever! And, the thin strip you slide the excess band into rubs the skin painfully, so I removed it.

I'm really liking the Martian Notifier watch. I currently have a Samsung Galaxy Gear Neo sitting in a drawer. This is my watch of choice. The simplicity of the design is very efficient. Kind of old school meets high tech. This watch looks great, especially after I upgraded to a very nice black leather band to match my black face watch. As others have mentioned, the watch cannot stand water. I walked through a parking lot in a light rain shower and shortly after noticed condensation formed on the inside of my watch face. My wife suggested placing my watch in a zip lock bag full  of rice overnight. Apparently the rice draws moisture out and saved my watch. My watch looks good as new now and I am very careful not to get it wet again.

I loved this watch until it stopped working about 2 months ago. I tried getting it going again by leaving it in light intentionally which helped for a while and then it just quit. I had it for 3-4 years,  not exactly sure and can't find the receipt so I could not take advantage of the lifetime warranty provided by the seller. Might have been fixable but not in my area,  so I bought another one last week! I love the simple style,  two colors and not having to worry about battery changes. On the other hand,  I hope this one will last longer than the last one.

Pros: This is cool watch. I like design, light weight and the fact that I do not have to charge it. People have been complementing it and were stunned when I told them it is actually fitness tracker.

Cons: after three months glass shuttered out of blue. Customer service was excellent and shortly I received replacement. One and half year later the same things my happened. This time out of warranty I was given discount for next purchase.

Conclusion: I missed heart rate monitoring since I have been wearing it during exercises (swimming, running, cardio, even MMA...).  I will be purchasing HR once available.

I could NOT get this band off my Gear S2 after I put it on. Now I have to return my watch to Samsung to see if they can get it off. I hope this didn't void my warranty! I'm so ticked off!

my girlfriend bought me this watch and i love it, but my work environment isn't very suitable for watches so it sits in my pocket a lot (with my keys). the band has suffered a bit of damage (all cosmetic) but still holds strong, and the face of the watch seems to be the most scratch/scuff resistant.

update: I forgot about this review or I would've updated it earlier, but about 3 weeks after I got the watch the battery died, so we got it replaced. I don't know if it was the watch or the guys who repaired it, or just the construction of the watch itself, but it crapped out hard. Changed the battery again and still nothing, then the second hand fell off somewhere between changes. It sits in my closet somewhere now since I have given up on it

I have been using this new watch for less than a month when I take my walks.  I love that it tracks both my steps and I can check my heart rate against my hi-lo settings (based on my age) and ensure that I'm in "the zone".  It took me awhile to figure out how to get my personal info programmed into it correctly, but it was working great until yesterday.  The heart rate monitor just stopped working when I touch the face.  I'm assuming it may need a new battery?  Still need to figure out how to take my steps and translate them to miles.  The jury is still out on this one.  I think I'd prefer to have one that I could interface the info into my PC to track my progress.

You would be wise to check its compatibility with your particular phone.  I mistakenly thought that it would be okay with my Android version and bluetooth but alas it is not.  It does not like Kyocera phones for whatever reason.

So essentially I have a $40, 100m analog watch.

I will stick with my non-waterproof Gear S2 because despite not being waterproof, it does everything.

But very disappointed that the watch is phone selective.  BIG MISTAKE!

It is a good looking watch with a good battery life. But it has a limited capability compared with Samsung Gear 2. No alternative way to install music apart from Google play music sync. I am in the region where no music from the Google store available to purchase so it can not play any music. No actual phone call from the watch can be done, only dialing from the watch then pick your phone up which is senseless to do so.

This is a wonderful watch has a lot of great features. I purchased this watch in 2013. I have not worn the watch everyday however it was a sturdy watch until 2 weeks ago 2017. The band had broke and later realized that the band is almost impossible to replace.  However I'm greatful for the inventors of gorilla glue. I still love this watch even with the gorilla glue holding it together. I still prefer to grab this watch over my smart watches any day.

Although this has been my favorite smart watch (thus far, 05/15/15), the technology is a bit premature and buggy.  I would have also liked it more if it was a pure Android Wear device.  Samsung... STOP TRYING TO BE Apple!
