Editorial note

The Sunstech CELT15 presents itself as a functional smartphone, offering interesting advantages for daily use. Its built-in flashlight is a real plus for illuminating dark areas, and its modern black design gives it an elegant look that fits various environments. Weighing just 80 g and with compact dimensions, the CELT15 is easy to carry, ensuring a pleasant daily use. Moreover, the removable battery allows for easy replacement, thus extending the device's lifespan. However, the Sunstech CELT15 also has notable limitations. The lack of Wi-Fi connectivity restricts access to the Internet and online applications, while the low resolution of the rear camera (0.08 MP) and the absence of a front camera may disappoint users wanting to capture moments in photos or make video calls. Additionally, the 32 MB flash memory is insufficient to store a significant amount of files, although expansion via MicroSD card is possible. Finally, the 2-inch screen and the resolution of 176 x 200 pixels seem outdated compared to current standards. In summary, the Sunstech CELT15 is suitable for basic use, but its limitations in terms of features and performance may not justify the purchase for some users. It is advisable to consider these aspects before making a choice.
