*by I***N on 19 January 2026*

### ⭐⭐⭐⭐⭐ Great purchase

### ⭐⭐⭐⭐ Great watch for the price but the backlight is only on one side
*by M***W on 6 November 2024*

I’m very happy with the watch so far and wear it every day for work. At 15 quid it’s cheap enough that damaging it won’t matter. So far it’s taken a couple of good hits and it’s still going strong without a scratch. The strap is comfortable and isn’t showing any signs of wear so I’d say it’s going to last. It’s been showered in water a fair bit and it’s definitely waterproof so far. The only small thing that bugs me a little is the backlight is not actually “behind” the face, it’s like a very small led to the left side of the face. It only lights up the left half of the watch which doesn’t let you see the minutes when it’s very dark in the early hours. Other than that small issue the watch it great.
