In this wireless gaming keyboard review, the Logitech G915 X LIGHTSPEED TKL comes across as a belated and underwhelming effort to compete with the expanding lineup of HE custom gaming mechanical keyboards from China. Despite its short key travel for the quick response and zero-lag LIGHTSPEED technology, Logitech lags in the competitive gaming keyboard market.
The switches transition from low-profile 2-mount to cylindrical MX stems, offering three options: Clicky, Tactile, and Linear. A new KEYCONTROL shortcut toolkit adds 15 programmable buttons. However, the Logitech G915 X LIGHTSPEED TKL still falls short compared to HE custom gaming keyboards in every aspect.
Logitech G915 X LIGHTSPEED TKL Wireless Gaming Keyboard Review
Design
A low-profile design is far from optimal for a typing experience or sound. From a gaming perspective, it is acceptable—thin, light, compact, and effective for gameplay. However, gamers today care not only about fast response times but also about typing feel and sound quality.
Although the top of the G915 X LIGHTSPEED TKL is made of aluminum, the bottom is plastic. However, the sturdiness and durability of this wireless TKL mechanical keyboard are not particularly evident. When I type, I can hear faint, unidentifiable noises from the back of the keys, suggesting some hollowness inside.
The Logitech G915 X LIGHTSPEED TKL features a low-profile design, standing just 2.2 cm tall. At the bottom, it includes two adjustable kickstand legs to modify the typing angle. These legs allow for two tilt options, raising the angle from 4 to 8 degrees. While a steeper angle can enhance typing comfort, the ideal angle ultimately depends on personal preference.
The upper-right corner features the familiar metal multimedia wheel for volume control, which can also be customized with commands through the G Hub software. Additionally, there are eight rubber function and mode keys evenly distributed on both sides. The Lightspeed antenna cluster is located right in the middle of the key, and the outer left corner will have the G logo with RGB LED according to the customization of the entire key.
The power button and Type-C charging port are positioned on the top edge. The bottom features two kickstands for adjusting the typing angle and a slot for the 2.4G dongle. This practical design helps prevent gamers from frequently losing the receiver, offering peace of mind.
Overall, the design of the G915 X LIGHTSPEED TKL wireless mechanical keyboard feels familiar and somewhat dull, continuing the style introduced by Logitech’s earlier low-profile gaming models, the G913 (2019) and G915 (2020).
New GL MX switch and ABS keycap
At first glance, I wondered, “How does the LOGITECH G915 X LIGHTSPEED TKL differ from the previous G913 or G915?” However, after using the keycap removal tool, I noticed that this year’s new low-profile switches from Logitech felt a bit unusual.
This year, many brands such as Lofree and Keychron, which are two typical brands that often make low-profile keyboards, have switched to using MX-axis switches (cross-axis) instead of the traditional 2-mount switches. If you find it confusing, you can see the image below of the 2-mount GL switch on Logitech’s previous G913 and G915 to compare with the new MX switch on the current G915 X LIGHTSPEED TKL.
Using the MX switch type offers several benefits. First, it allows for easy keycap changes since most modern mechanical keyboard keycaps feature cross-slot mounting feet. Second, it is more durable than the traditional 2-pin switch type. Third, it provides deeper key travel—up to 3.2mm compared to 2.7mm on older 2-pin switches—resulting in a smoother pressing experience.
Logitech’s GL MX switches on the G915 X LIGHTSPEED TKL are available in the usual three options: Clicky Blue, Linear Red, and Tactile Brown. Our wireless gaming keyboard review unit features the Tactile version with 3.2mm of key travel. However, the gaming and typing experience is underwhelming due to the thin keycaps made from standard ABS plastic.
KEYCONTROL
The Logitech G915 X LIGHTSPEED TKL offers multiple connection options, including three wired modes, a 2.4G receiver, and Bluetooth 5.2, but lacks meaningful upgrades and fails to deliver consistently stable, high-quality performance. However, Logitech highlights its included toolkit as an innovative enhancement for this tenkeyless wireless mechanical keyboard.
Specifically, in the Ghub software, there will be an Assignment section where users can assign commands to function buttons according to the default layout of the key. When switching to the FN (Function) tab, there will be an option of 15 buttons scattered throughout the keyboard. In general, KEYCONTROL offers more buttons for assigning commands, enabling more versatile usage.
KEYCONTROL, as advertised by Logitech, is a versatile toolkit that allows you to assign any command to its 15 designated buttons. You can also assign shortcuts to open applications or switch between software windows (such as Alt+Tab) with a single button press. Additionally, it’s useful for office tasks.
Even professional gamers rarely use macro button adjustment features. The Logitech G915 X LIGHTSPEED TKL provides plenty of gaming-focused buttons, including Game Mode, Bluetooth and 2.4G switching, and customizable LED effects. However, few games require extensive macro button configurations.
Gaming and Typing
As mentioned earlier, the Logitech G915 X LIGHTSPEED TKL features the new GL MX switch paired with standard ABS plastic low-profile keycaps. This combination makes the typing experience on this wireless TKL mechanical keyboard feel somewhat less enjoyable.
To explain why it’s uncomfortable to use, let’s revisit the low-profile design. A design that is too thin isn’t ideal for a comfortable typing experience. The inside of the key is still hollow, and the type of switch used is Tactile, giving a typing feeling that is not consistent and sturdy.
ABS plastic keycaps contribute to a rattling sound, making the typing experience feel somewhat shaky and unstable on each key. Although the 3.2mm travel is longer than usual, it is much smoother than traditional low-profile keys. However, it still falls short of expectations.
Using 10 Fast Fingers software, I average 110 words per minute on a regular custom mechanical keyboard. However, on the G915 X LIGHTSPEED TKL, it drops to about 80 words per minute. This is partly due to the unfamiliar typing feel and the overall subpar typing experience.
For gaming, the tactile switch doesn’t suit my preferences. I prefer a solid bottom-out feel right from the first press when using movement and attack buttons. Tactile, on the other hand, gives the sensation of pressing up to two beats. This occurs because the switch column inside has a notch in the middle. While it feels more realistic, it sometimes fails to activate moves or items when needed.
For better and faster gameplay, opt for the red linear switch version. It delivers quicker response times and an improved typing experience during play.
Battery life
The LOGITECH G915 X LIGHTSPEED TKL offers up to 1000 hours of battery life with the RGB LED turned off. However, with continuous LED usage, the battery life drops to 42 hours, similar to the previous G915 model, which offers around 40 hours with the LED on.
Final line
LOGITECH G915 X LIGHTSPEED TKL has given me an experience that is not really perfect, both in terms of typing feel and gaming experience on the Tactile Switch version. Logitech really needs to try harder, more than just changing the switch and integrating KEYCONTROL. Something bolder, so as not to be crushed by the HE custom gaming mechanical keyboards in the near future.
