The Nerunsa Smart Watch is a feature-packed budget smartwatch with reliability questions, best for budget buyers. Rated 3.6 out of 5 across 127 user ratings. The main drawback: reliability is uneven. We scored it 3.3 out of 5.
You get a lot of watch for the money, including a sharp 1.85-inch AMOLED screen, Bluetooth calls from the wrist and long battery life, but that value depends on getting a unit that lasts, since some stop working completely.

Charge the watch fully before setting it up.
Install the watch's companion app on your Android phone or iPhone and allow Bluetooth and notification access.
Pair the watch from the app. It connects quickly with both Apple and Android phones.
Pair the watch's calling function with your phone's Bluetooth so calls can be answered and made on your wrist.
Select which apps send notifications, and add your usual sport modes for quick access.
Only for some buyers: we score it 3.3 out of 5. The Nerunsa P66D packs a sharp AMOLED screen, wrist calling, 100+ sport modes, health tracking and long battery life into a budget watch, and it handles notifications and everyday tracking well.

Reliability is uneven, with some watches stopping altogether. Call speaker could be clearer.
Wipe the sensor and band clean regularly.
Wear the watch a finger's width above the wrist bone, snug but comfortable, and keep the sensor clean. Readings are most stable during steady exercise.

The Nerunsa P66D packs a sharp AMOLED screen, wrist calling, 100+ sport modes, health tracking and long battery life into a budget watch, and it handles notifications and everyday tracking well. Sensor accuracy is fine for trends. The real risk is reliability, with some units failing completely, so buy it where returns are simple.
A lot of smartwatch for the money, with an AMOLED screen and calling. Set it up promptly, keep the return window in mind, and choose a more established brand if you need proven durability or accurate training data.
