Kieslect KS2 Pricе
The watch is available through Kieslect’s official store on AliExpress or the company’s official website for $25.15, with slight variations depending on the region.
In terms of pricing, the Kieslect KS2 sits roughly in the middle – between simpler fitness bands like the Xiaomi Mi Band 10 and more fully featured smartwatches such as the Apple Watch SE.

Package contents
The watch comes with a fairly well-rounded package.
In addition to the charging cable, the package includes two interchangeable straps:
- Standard black strap with a classic buckle
- Black strap with blue accents and a magnetic clasp
The box also contains a screen protector. The charging cable is proprietary, so it’s best not to misplace it.
What the Kieslect KS2 Can and Cannot Do
Let’s start with the limitations of the Kieslect KS2, which are typical for devices in this class and price range:
- No support for third-party apps
- No SIM or eSIM functionality; calls can only be made when paired with a smartphone
- No built-in GPS; route and workout tracking requires a paired smartphone
- No NFC, so contactless payments are not possible
- Limited memory for watch faces (only 9,216 KB), allowing up to six faces at a time. Adding new ones requires deleting existing faces.
Let’s move on to the pleasant stuff – what Kieslect Ks2 can do. The smartwatch can:
- Making and receiving calls via the built-in speaker and microphone
- Access to Amazon Alexa voice assistant
- Displaying notifications from your smartphone
- Tracking steps, distance, and overall daily activity
- Monitoring heart rate, blood oxygen levels, and stress levels
- Tracking sleep quality and women’s health cycles
- Reminders to move or stretch
- Acting as a companion during workouts
It also includes standard features like alarms, weather updates, and control of smartphone music and camera.
Additionally, the Kieslect KS2 includes several workout programs that can, for example, help beginners start running correctly. These programs provide guidance on when to switch to walking, when to speed up, and the target heart rate range to maintain during exercise.
Design and Materials
The Kieslect KS2 has a typical smartwatch appearance. It features an aluminum frame (available in black or gray), a plastic back cover, two physical buttons, and a touchscreen – a standard combination for devices in this category.
The round “crown” rotates, serving not only as a button but also as a scroll wheel for navigating the watch interface.
The speaker for calls is located on the left side of the watch.
Charging connectors – on the rear panel above the sensor unit.
A clear advantage of the Kieslect KS2 is its ability to use any 22 mm strap, thanks to a standard attachment mechanism.
The watch itself is quite lightweight, weighing around 50 g including the strap, making it comfortable to wear throughout the day.
Water resistance is rated at 3 ATM, allowing for swimming in a pool or taking a shower – but without overdoing it. The watch even includes a dedicated setting to clear water from the speaker.
If the design of the Kieslect KS2 feels too standard, you might consider other models from the brand, such as the Kieslect L11.
Display
The watch features an AMOLED display with a resolution of 410×502 pixels. The screen is protected by glass, although the manufacturer does not specify the type. During testing, I was unable to scratch it.
The Kieslect KS2 display makes a strong impression. It is easily readable both indoors and outdoors. The touchscreen is sufficiently sensitive, and the interface responds instantly to gestures and inputs. The manufacturer claims a refresh rate of 60 fps.
An always-on display (AOD) is also available – a feature not always found in watches at this price point. The watch face for AOD can be selected separately.
Screen brightness can only be adjusted manually across six levels; there is no automatic brightness control.
The display also attracts fingerprints quite easily, so it’s recommended to use the included screen protector.
Interface and Controls
The Kieslect KS2 interface is generally intuitive. Pressing the “crown” opens the app menu, while pressing the other button brings up the workout menu.
Horizontal swipes allow you to switch between screens displaying useful information, such as activity, steps, heart rate, and weather.
Swiping down from the top, just like on Android or iOS, opens the control center with quick toggles.
Swiping up from the bottom opens the notifications menu. I had no issues with how notifications are displayed – they appear correctly in both Ukrainian and English. Ideally, it would be nice to interact with them directly, for example by using quick reply templates for SMS or messaging apps.
Additionally, when there are too many notifications, it can be difficult to scroll all the way to the bottom to reach the “Clear All” button.
Companion App
I used the watch paired with an iPhone 11. The official app, KS OS, is available on the App Store. One convenient feature is that it syncs collected data with Apple Health.
The app has four main screens. The first screen provides a detailed view of physical activity and health-related information.
The second screen allows you to start a workout and edit goals for each type of exercise.
The third screen is dedicated to watch settings, and it also allows you to log in to your Alexa account if you plan to use the voice assistant.
From this screen, you can also access the watch face store and download any styles you like.
Overall, the selection of watch faces is quite good, so most users should be able to find something they like.
The fourth screen in the app displays various achievements and rewards.
Battery Life
The Kieslect KS2 can be surprisingly impressive in terms of battery life. With Always-On Display turned off, my watch lasted 17 days on a single charge. I didn’t track sleep with it, had an average of three workouts (walks) per week, and received a regular stream of notifications.
From my observations, enabling Always-On Display significantly speeds up battery drain, so I eventually turned it off.
Based on average figures, the manufacturer states that the 300 mAh battery can last up to 9 days in normal use and around 96 hours in active mode. When used purely as a watch, the claimed battery life is up to 40 days.
Personally, I find this level of autonomy much more convenient and reasonable compared to the one-day battery life of an Apple Watch, which is a definite plus for the Kieslect KS2.
A full charge takes approximately 2 hours.
Overall Impressions
Before using the Kieslect KS2, I had the latest-generation Apple Watch SE, and before that, a variety of Xiaomi devices. Compared to these, the Kieslect KS2 sits somewhere in the middle.
Unlike the Mi Band, the KS2 has a larger display, making it easier to view notifications. The ability to answer calls and talk directly through the watch while the phone charges in another room has proven very convenient on multiple occasions.
Unlike the Apple Watch, the Kieslect KS2 does not support third-party apps, which can sometimes feel limiting. I would have liked to have alternative voice assistants besides Alexa, or the option to remove Alexa to free up more memory for additional watch faces. As a trade-off, however, the KS2 offers excellent battery life – comparable to the Mi Band, which I appreciated for its simplicity and endurance.
Aside from limited customization, the Kieslect KS2 occasionally experienced unstable connections with my phone. This may be related to iOS and its power-saving algorithms. I encountered situations where, during a walk with my phone in my pocket, the watch would warn at the start of a workout that it wasn’t connected to the phone and had no GPS signal. Similarly, when I misplaced my phone at home and tried to use the watch’s “Find My Phone” feature, it reported that it was not connected.
These situations were infrequent, but the manufacturer should definitely address the stability of the connection between the watch and smartphone. It’s possible that a software update could resolve the issue.
Conclusion
Overall, the Kieslect KS2 leaves a positive impression.
The watch makes it easy to view notifications and can handle incoming calls when your phone isn’t immediately at hand. It can also serve as a capable trainer and motivator for tracking step counts and calories burned.
Rounding out the package are a high-quality display, the ability to swap straps for any 22 mm option, and impressive battery life. At $$25.15, the Kieslect KS2 offers solid functionality, and snagging it on a discount can make the experience even more satisfying.
