I'm not sure if they would work out for either I had my first Neo replaced by Samsung because it looked like the cover glass was coming off. . Then as now I was asked if the device got wet. It's like yeah it got wet it's a watch water splashes on it when I was my hands. Now the replacement Gear 2 Neo is doing the same thing.
Another down side I have noticed is that it totally takes over the S-Health App. If you leave the watch behind, and just take your (in my case Galaxy S5) the pedometer stops as soon as you are out of blue tooth range. You can disconnect it but it's a pain and you often loose your fitness data for the day.
Had a ben given one to try out for a while I would have never bought it. It might be goos for office workers, but I'd have to say most others not so good. Oh I'm a Pharmacy Technician in a hospital so I get a lot of walking done in a day.
