Acer Extensa 15 EX215-51-56UX
Acer has introduced its next invention, the Extensa 15 EX215-51. This product can be simply viewed as a 15.6-inch office laptop. The system is powered by a Comet Lake processor. This laptop carries a weight of 1.9 kg and a thickness of 2 cm, which makes this Extensa a much lighter and thinner laptop than similar models. As for the design, Acer has relied completely on black plastic, as no high-end materials such as aluminium or magnesium has been used to form the chassis. It is a an all-black plastic composition. While the surfaces on the back of the lid and the top base unit are smooth and matte, the sides and bottom of the device are quite textured. The battery is fixed and not removable, which might be a drawback for some users. However, the single added advantage of such a battery is the longer battery life, which allows for whole-day usage without the need to recharge. This is definitely a rather favorable laptop for those looking for a thinner laptop with minimum recharging.
This product definitely lacks in terms of rigidity, as the base unit yields to pressure on the left and right areas of the keyboard; it is also susceptible to twisting. The lid is not an exception, as it can also be twisted without much force. This leads to slight distortions on the display as well. Some even went on to describe the Acer Extensa 15 EX215-51 as a workhorse with a disappointing display, as some users pay extra attention to and demand an awesome display for a better user experience. The TN panel that has been incorporated within the display is obviously outdated and results in poor contrast ratio and narrow viewing angles. This is a huge drawback and disappointment, as such a poor construction is not reflected in the price range in which the Extensa 15 EX215-51 has been marketed.
Apart from that, the Extensa 15 EX215-51 incorporates RAM which only runs in single-channel mode. This is due to the fact that there is only a single RAM slot with no pre-installed, soldered RAM which prevents the possibility of enabling dual-channel mode. This laptop also does not cater for extra graphic power, since there is no dedicated video card incorporated within it. Some reviews even claim this Extensa model produces noise when completing demanding tasks, which might just intrude on the whole user experience overall. The main drawback with this model has to be the low return for such a demanding price, which could be rather disappointing. However, this Extensa can definitely perform general basic tasks easily without any disruption due to its long-lasting battery, as there is no need to keep recharging.

Strengths of the Extensa 15 include the Core i5 processor, NVMe SSD, low noise level and the moderate surface temperatures. The system's biggest weakness is the display. At a price of 650 to 700 Euros (~$705 to ~$759), the device is not exactly a bargain, either.

The Extensa offers a powerful Tiger Lake processor at a budget price point. The dark, low-contrast TN screen with unstable viewing angles is the computer's big weakness. A Windows operating system does not come included in the scope of delivery.

The Acer Extensa 15 (EX215-33) may be suitable for home, office, or school usage if you pick the max-out configuration. This includes a 1080p IPS display, an eight-core CPU, and 16GB of RAM. The performance of the Intel Core i3-N305 seems sufficient for normal tasks since the chip can sustain a 2.05 GHz clock even in prolonged periods of max processor stress like 3D rendering. This reminds us that the comfort during long loads is good because the CPU doesn’t get hot, as well as the keyboard. The fan is also quiet. The Full HD TN display (NT156FHM-N61 (BOE07CB)) should be avoided like the plague. The only good thing about it is the lack of PWM usage. However, the color coverage, the maximum brightness, and the contrast ratio are really bad.

The Extensa 15 (EX215-55) could be a good daily driver for budget-conscious users. Even the Core i3-1215U is just okay for work if it’s accompanied by at least 16GB of RAM in dual-channel mode and a decent SSD. Just be careful not to pick a machine with a TN screen. The 1080p TN display (B156HTN06.1 (AUO61ED)) disappoints. Its viewing angles are super narrow, the color coverage is low, the contact ratio is just 370:1, and the out-of-the-box color accuracy is absurd (average dE 9.3). At least you can fix the accuracy with the aid of our “Design and Office” profile. The EX215-33 iteration of Acer Extensa 15 may tempt value-seeking users with a pleasant price, high CPU clocks during long stress, good upgradability, and decent port selection.
