I have bought a total of 4 Trust Primo mice for 3 laptops. They don't break, they don't malfunction, and they work perfectly. After a certain period of inactivity (maybe a minute, I haven't measured it), they go into sleep mode to save battery. They work just as well in both Windows and Linux Mint. At one point, I got angry and threw the mouse against the wall, and it broke apart. I assembled it again (nothing was broken) and it worked normally. At some point, I broke the USB during transportation, but that was the only loss I had. There is no reason to buy a mouse that costs more than the price of the Trust (very cheap). In April 2023, I bought another one which didn't work at all from the beginning.

I had it for many years, it had endured the worst: constant hits on the table, things being thrown at it (the computer would freeze because it was old and I would get frustrated with it), and yet it still worked!
It doesn't have side buttons, but for this price and if you don't mind moving the cursor for <- and ->, it's excellent!
Note: I bought the same one again, this one has a slightly better sound than the previous one, but the top battery is difficult to put in, its spring pushes it upwards, but with a little pressure, the cover goes in and it's okay.

I bought it 4 years ago for use with a laptop and I have been absolutely satisfied. I use it about 50 days each year with the laptop and I still haven't changed the batteries. So far it works perfectly. If it stays idle for a few seconds, it immediately goes into sleep mode, thus saving battery. Despite its small size, it has an excellent feel in the hand and is lightweight and extremely comfortable to hold. Compared to a Logitech Mouse M185, since I have both, it has a much better feel and grip in the hand.

UPDATE 16.08.2024: The mouse gave up after 6 years of operation. It started to have interruptions and the pointer would not appear on the screen intermittently until it eventually disappeared and stopped working altogether, while its light is on. I changed the batteries but nothing. It was purchased for €8. Nevertheless, for all the years it worked, it was flawless. I replaced it with the same one.

The mouse is perfect for regular use and it has fallen on me more than 10 times and it hasn't suffered anything!!!

I bought a mouse for myself and I was very satisfied with it. It worked perfectly, everything was great, so after a month I bought the same one for my mother. Now it has been six months and in four of them it stopped working for both my mother and me. I don't know the reason, but it definitely isn't the batteries, we changed them a hundred times.

Well, I have had this mouse for about 6 years and I have absolutely no issues with it. It has been very convenient for me since it is wireless and the mouse has a special compartment inside the cover to store the USB stick, making it easy to transport. It is lightweight and very durable. It has fallen many times and has not suffered any damage at all!! It's the best

I consider it a waste of money as it may be cheap, but it either doesn't work or experiences interruptions. I bought 3 and none of them worked properly for more than 3 days.

From the second day, the left button makes a small squeak when pressed, as if it needs lubrication. It's like it's touching the right button at some point. I do not recommend it at all.

Very lightweight and responsive, it suits me well as I handle it with my fingers and don't touch the palm at all. It's also great for gaming, although I don't play FPS games.

Update 20/08/2021
It simply stopped working... It had some minor interruptions which worsened over a period of 2 days, but I thought it was due to the battery. As soon as I changed several pairs of batteries, nothing happened. The light turns on and there is a response from the computer when I connect the USB, so something must have gone wrong with the wireless communication. What a shame...

Bought it somewhere around 7€. Honest mouse and convenient. I wanted it wireless and I liked its color. I have thoroughly enjoyed it.

Good and accurate response from the cursor, its noise is not annoying, quite comfortable although I would like it a little bigger.

I have had it for a very long time, around 4-5 years. I use it daily for many hours. The truth is that the clicks may sound a bit, but I don't pay attention to it nor is it bothersome. I change batteries every 4 months or so, maybe even more, depending on the usage during that period. Sometimes I use batteries that have been minimally used in Christmas decorations. It is small and if I need to do very delicate work, it is not the most comfortable thing, but for the 8 euros that I bought it for, I didn't want anything more. The external appearance has deteriorated a bit, it has something like "peeling" but I use it constantly so I understand it. It has fallen and nothing has happened to it!

I have had it for 4 years, maybe even more, and it still works without any problem despite the many falls. It was purchased for 8€.

For simple everyday use, it's worth its money, a little smaller compared to the photo, the clicks are heard without disturbance and the wheel is correct. It works perfectly at a distance of four meters, which I have it, and it has an eco mode for energy saving when not in use. Finally, the USB is inside the battery compartment

For its price, it is perfect. Also, I don't find it negative that the clicks can be heard. I have had it for over a year and I have only changed the batteries twice.

I already had this specific mouse permanently at the office for a year and I was extremely satisfied! I bought a second one for work from home due to quarantine. For its price, it's great! I use both of them on a wooden surface without a mousepad and they work exceptionally well.

I probably received a defective one... The next time I opened the laptop, it didn't recognize the USB, making it unfortunately useless.

The mouse is very good and fast, after a week of use the only thing that bothers me is the small size, otherwise it is excellent

Just received it so it needs space and not on all surfaces. I don't know if it's worth it, but it's better to give something more and get something worth it...

For simple use on a laptop, it does its job perfectly without any glitches. For anything more or something more professional, it won't suit you.

Definitely worth the money because it has a good feel in the hand, fast response. It is perfect for use with a laptop as well as a desktop computer.

I have the mouse for one day... It is really flawless and it is value for money.... It has amazing grip, size, and weight.... The buttons are minimally noisy without bothering me.... I haven't formed an opinion yet, but I think it is the ideal mouse!!

After daily intense use (8-10 hours) for office work and for over a year, the conclusions are that:
The mouse has in its favor the convenient shape and the fact that it deactivates when not in use with a fairly good response.
In its negatives, the worst is that it is demanding in terms of energy, as its batteries do not last more than 30-40 days, and also all the buttons are particularly noisy.

It looks like the Microsoft 3000, I have it for a few days, I have connected it to a smart TV so it responds perfectly. Plus, when you don't move it, it goes into eco mode. It's a good feature because you don't have to remember to turn it off.

As for the rest, time will tell. Value for money? 4/5/2019 After a couple of falls, it started to not respond. Generally, since the day I got it, it didn't work well on a polished surface (coffee table). Now, after about 3 months, the wheel is not working properly. I opened it and saw why it's so cheap... everything inside is plastic and the assembly is laughable. If you see how the wheel is placed, you will laugh. Anyway, you get what you pay for, at least most of the time.

The mouse is very good for use on laptops. It has an ideal size for small and medium hands, it has a nice grip, nice appearance, and instant response (talking about normal surfaces). The batteries actually last quite a long time, I have had it for 3 months with normal use and they still last. The package also includes batteries. The scroll wheel also has a nice grip and the appropriate resistance when turning it. It is recommended without any hesitation, especially for the price it costs (I bought it for 8 euros).

Very good for its price. It didn't bother me at all for about a year. Suitable for simple everyday use. It has energy saving. Convenient size, also for a laptop.

Very good for its price. Personally, I liked the color and the size. When we stop using it, it turns off to save energy. It takes 2 AAA batteries, definitely lasts for 6 months with daily use. The company is Dutch and has been in the industry for years.
