I bought one of these last time on impulse. It’s actually not terrible since it does appear to be rather water resistant. I have taken it swimming twice so far. The touchscreen is a mess when trying to use wet but the watch is fine.
It’s very responsive and the dpi of the scream is reasonable. No auto brightness but the highest brightness setting is fine in direct sun.
Heart rate sensor is adequit. Step counter is normal. I haven’t messed with any of the exercise modes. Battery life is excellent. There are a ton of watch faces.camera remote did not work with my s20. Music controls did.
It’s decent. I don’t think it is the deal 9f the century at $30 but it is a solid limited feature smart watch.
