How to test a computer mouse after purchase

Buying a new computer mouse is always a welcome upgrade. To make sure that the product fully meets your requirements, we recommend that you do a small initial test drive. This will help to immediately identify design flaws or defects. There is no generally accepted methodology, therefore we will talk about the main points that everyone can check on their own.

Visual inspection and mechanical check
As a rule, the new mouse has the perfect appearance. But there are times when it is obvious that the box was unpacked earlier and the gadget was used for demonstration or other purposes. Of course, you should inspect the mouse and packaging as carefully as possible in the store, but do not forget to do this after the purchase. Pay attention to a few things:

No scuffs, scratches or dents. The new mouse should be free of any plastic coating defects. All labels must be legible and free from damage. Even slight abrasions indicate that the mouse has already been exploited.

The integrity of the power cord. In packaging, the wire is usually complex and not visible to the eye of the buyer. In rare cases, kinks can be critical, and the tissue braid is torn. Pay particular attention to the place where the wire is connected to the body.

The condition of the sliding pads. The pads of the new computer mouse are smooth, without streaks and scratches, and also do not move from side to side and do not come off.

No dirt in crevices and gaps. One of the signs that the mouse has already been used is dust and dirt in the gaps between the panels and in other small holes.

If everything visually suits you completely, proceed to checking all moving parts – buttons and wheel. Make sure the mouse keys are not sticky or sticky. The wheel should roll smoothly, but at the same time with discernible “steps”. Also, be sure to flip the wheel if it has a button.

Ergonomics and grip
It is better to try on a mouse at the time of purchase. As soon as you connect the device, you will be able to appreciate the ease of use. At the same time, keep in mind that the length and height of a computer mouse directly affect the usability, depending on the type of grip. Do not be alarmed if in the first hours your hand starts to hurt – this is normal, especially if the new one differs from the previous one in shape and size.

Be sure to check what surfaces the mouse works on – a wooden table, glass, rugs made of different materials. For example, optical mice won’t work on perfectly smooth surfaces like glass. We talked in more detail about how optical and laser mice function earlier.

Mouse testing
First, make sure that absolutely all basic keys work correctly – these are the left and right keys, as well as the wheel. Additional buttons may not respond to pressing until you program them.

You can use this resource to check for double click . It allows you to evaluate the work of all basic, as well as some additional keys, depending on the mouse model. The site shows the time since the last keystroke, and also registers a double actuation. New mice shouldn’t have any double clicks. Alternatively, this site will do .

Next, you can check the DPI for your mouse. But first you need to find out what DPI is currently active for your mouse. This information is spelled out in the specifications or in the technical documentation. If the mouse has DPI switching modes, then set the lowest one. As a rule, in such models, a light indicator indicates the set mode.

Second, you must turn off the Increased Pointer Precision option in Windows settings. You can find it in the Mouse section, Pointer Options tab. When doing this, note that the speed slider should be centered.

Next, you need to prepare a small piece of paper, where you should measure exactly one inch (2.54 cm). Then go to this site . In the settings, it is enough to set Target Distance = 1, and the unit of measurement in Inch. Leave the rest of the parameters unchanged.

Position the cursor over the red pointer on the scale, hold down the left button and, using the measuring sheet, move the mouse exactly one inch to the right. For convenience, you can use a ruler or other landmark, including patterns or inscriptions on the mouse itself.

In our test for the A4Tech OP-35D mouse, we got an average result of 815 DPI. According to the technical documentation, 800 DPI is declared for this model. If all the conditions are met and a sufficiently accurate measurement, a value can be obtained with a minimum error. This way, you can test the different DPI modes if you have a game model.

Also, online services allow you to estimate the frequency of sensor polling – this site will help . You can see the value in real time, and the site also records the maximum value of all measurements. Please note that for most office models, the polling rate does not exceed 100 Hz. For gaming mice, this parameter can range from 250 to 1000 Hz.

Firmware check
In models from the middle and high price segment, some of the parameters, backlighting and soft keys can be configured using proprietary software. Everything here is individual – proprietary software may differ in both functionality and compatibility with various OS.

Operating system Microsoft Windows 10 Home 8 499 *
We recommend checking the following points:

sequentially program each of the additional keys by performing testing in games or specialized programs;
check the operation of changing backlight modes;
make sure that changing DPI modes, sensor polling frequency works correctly;
create multiple profiles and check each one;
record and test macros.
