Graphical Vs Comparison
Wow! The Monkeys 🐒 learnt to make Graphs!
Physical Characteristics (mm, grams) |
|
Sensor Characteristics (0 ➡ 100%) (worse ➡ better) |

Latency Characteristics (0 ➡ 100%) (worse ➡ better) |
|
Other Features (0 ➡ 100%) (worse ➡ better) |
Graphs Description | The Physical Characteristics comparison is just a viewable representation of the devices' length, width, height and weight. Sensor, Latency and Other Features are, instead, computed within the range 0-->100, taking into account if the variable is getting better with the increase of its value (e.g the highest max DPI, the better it is) or vice versa (the lowest Click Latency, the better); for example, a score of 50 for both devices means they are equal, scores of 70 and 30 mean that first one better. So, the data are homogeneous to provide immediate meaning, higher bar(s) means better value(s). An empty graph means that there is not enough data to compute that comparison (one value or both are missing). |

Razer Basilisk Essential | Thermaltake Level 20 |

Final Vs Words
Aiding our visitors to the final choice between the mice.
This final paragraph will help you in the decision making process, between Razer Basilisk Essential and Thermaltake Level 20, and in selecting the mouse that is performing better and best suits your needs. We are aware that every user has own needs and preferences, due to this each mouse could be better for some features and worse for other ones. The purpose of the text is to highlight this possibility and generate an "overall score" for a purchase decision.
First of all, both mice share the same utilization aim, Gaming mouse. The mice are aged similarly, 5 years old, being released in the 2019.
• Dimensions, Weight, Ergonomy 📐⚖️🫳
When it comes to evaluate mice dimensions, you should take into consideration the size of your hand and check if it would properly fit it or not. In this case, you should check which mice would be the fittest. Compared to Level 20 mouse, Basilisk Essential is ~4.35 mm (or ~0.17 in) Shorter, ~7.21 mm (or ~0.28 in) Narrower and ~3.64 mm (or ~0.14 in) Lower, which makes it, overally, 15.2 mm (or -0.60 in) moderately smaller and better suiting tinier hands.
Considering the weight, Razer Basilisk Essential is 27% lighter, a difference of 35.90 g (0.08 lbs), which can be considered quite significant. We do not express a particular preference for heavier or lighter mice, being this a completely personal objective preference. Anyway, both mice does not offer weight personalization .
Regarding the Ergonomy, Basilisk Essential is meant to be Right-handed while Level 20 is Ambidextrous. They offer different grip, Palm grip, Fingertip grip by Basilisk Essential while Level 20 has Palm grip, Claw grip, Fingertip grip; this last one can be considered more adaptable, with a number of grip possibilities equal to 3 instead of the 2 offered by the other one.
• Sensor and Latencies 🐭⏱️
Let's now compare Razer Basilisk Essential sensor with the one of Thermaltake Level 20. The two mice share the same sensor technology, that is Optical, but different sensor model: PAW3328 equipped by Basilisk Essential and PMW3389 used by Level 20. It is very important to say that, although tech and model sometimes coincide, the assembly and composition of interior circuits might result in different specs and latencies.
Resolution, Max Acceleration and Max Tracking, Polling Rate and Lift Off
The mice offer different resolution range (DPImax - DPImin), the Basilisk Essential provides 6300 DPI/CPI, while Level 20 offers 15600 DPI/CPI, meaning that the last one has way larger range. Consider picking up the one having the sensitivity range that mostly suits your needs, depending on the aim (Gaming/Business) but also the kind of game you are going to use it mostly (e.g. FPS is different than RTS or MOBA). If you need a higher precision mouse, meaning that for the same length of shift the mouse will recognize more movement, "reading" more dots per inch and, in other words, will move faster on the screen, Level 20 is offering 60% better Max Resolution, 9600 More DPI/CPI.As for the Maximum Acceleration, which measures the maximum pull force in G(s) that the sensor can trace before inconsistencies occur, Level 20 shows a better value, 50 G, a moderate difference of 20 G. Going on, taking into account the Maximum Tracking Speed, the velocity (inches per second) that the mouse can move at before it starts to loose track and cause anomalies, Level 20 shows a preferable value, 400 IPS, a significant difference of 180 IPS. Take into account that max G and max IPS mostly affect activities requiring very fast mouse shift, together with the shift latency that we will analyse further in this section.
Basilisk Essential has a Polling Rate of 1000 Hz, in other words it reports data to computer 1 time every 1.00 ms, while Level 20 is characterized by 2000 Hz or an input every 0.50 ms, making this last one having 50% better Polling Rate. Lastly, the Lift Off distance of Basilisk Essential shows an higher value, 2.5 mm, a significant difference of 0.70 mm. Anyway, they do not offer adjustable lift off distance through software.
Click and Shift Latencies
At the moment there is no available data to compare the mice click latency, since the data of Level 20 is missing. We apologize for the inconvenience, you can request priority data update through the contact page. However, Basilisk Essential has a click latency of 25 ms which can be considered not so good, compared to a medium quality mouse. Anyway, we feel it is important to underline that the differences in latencies are often more perceptible from the machine's point of view rather than human's, reducing the real impact of these values and deviations. At the moment there is no available data to compare Basilisk Essential and Level 20 shift latency. Contact us to request priority data update.
• Other Features 📎
Let's now have a look, finally, to the general features of the two mice. They are equipped with different Switch Technology, Basilisk Essential has Unknown while Level 20 has Omron; moreover, the lifespan of first mouse is 20 millions clicks while the second is 500 millions clicks, 60% worse Lifespan, a difference of 30 millions clicks that can be evaluated very significant. The Feet Material is the same, PTFE. Considering the available Number of Buttons, 7 offered by first mouse and 8 offered by the second one, a small difference of 1 that can be considered important or not depending on the utilization purpose. In the end, the features offered by Razer Basilisk Essential are DPI Indicator, RGB Lighting, Customizable RGB, while Thermaltake Level 20 is giving On board Memory, DPI Indicator, RGB Lighting, Customizable RGB.
