Buy the KIPTUMTEK Smart Watch.

Two budget smartwatches doing the same job, one costs a third of the other, and the expensive one does not do enough extra to earn the gap.

What was compared

KIPTUMTEK Smart Watch for Women Men, Fitness and Sleep Trackers with 1.83" HD Touchscreen,... — $17.99
Smart Watch for Women, Answer/Make Call, 1.32'' AMOLED Ultra-Clear Screen | Fitness Tracke... — $64.98

1. Same job done for a third of the price
Both watches track steps, sleep and heart rate and both take Bluetooth calls. The aeac watch charges $64.98 for that, KIPTUMTEK charges $17.99, and neither does anything the other genuinely cannot.
2. A screen you can actually read at a glance
KIPTUMTEK runs a 1.83 inch display against the aeac's 1.32 inch. On a wrist, that extra room is what lets you read a text or a workout summary without squinting, which is most of what a smartwatch screen gets used for.
3. IP67 already covers what you actually do
IP67 handles rain, sweat and hand washing without issue, which is 95 percent of what a watch faces day to day. Unless you are swimming laps and need the aeac's 3ATM rating specifically, that upgrade never gets used.
4. Higher owner rating, not just a bigger crowd
KIPTUMTEK sits at 4.4 to 4.6 stars against the aeac's 4.3, and research even flags recurring sync and charging complaints on the aeac. A smaller review pile with a better score beats a bigger pile with more gripes in it.
5. Yes, AMOLED and more reviews. Doesn't flip it.
The aeac has a genuinely nicer AMOLED panel and a huge 5,292-review base, both real advantages. But neither fixes documented sync issues, and paying triple for contrast on a fitness tracker only makes sense if screen quality alone is your top priority, which it is not for most buyers.
