VicTsing MM057 2.4G Wireless Portable Mobile Mouse Optical Mice with USB Receiver, 5 Adjustable DPI Levels, 6 Buttons for Notebook, PC, Laptop, Computer, MacBook - White

This mouse has 2 major flaws. The first is no on/off switch. That may not be an issue if you just leave the mouse on a desk, but if, like me, you put your laptop to sleep and then put the mouse in a bag or aside somewhere, then you will find that the movement of the mouse wakes your laptop back up. The second flaw is the shape. It feels nice in the hand until you need to lift the mouse and move it over (if you dont think you do that, just pay attention next time you are using one). The shape makes it awkward to lift up. I ended up getting a different mouse to replace this one. Update: VicTsing contacted me after I wrote this review and offered to replace my mouse with a different model. While it doesnt change my opinion of this mouse, the replacement is a much better mouse, and I am very happy with it (https://www.amazon.com/dp/B074XFFKDG). I was going to just toss the mouse and write it off as a bad purchase, but ended up with a mouse that I really like -- Ill give credit to VicTsing customer support for making that happen.

Im not sure if I got a defective mouse, or if all of these positive reviews are fake, but this mouse is terrible. 1. The scrolling jumps up and down no matter which direction you scroll. Yes Ive tried cleaning out the sensor a billion times, it doesnt help. 2. There is periodically lag or unresponsiveness. 3. The accuracy is fairly poor, and it has a very annoying momentum drag which makes it impossible to make precision movements. Even something as simple as dragging up a slider bar is impossible, because it takes forever to get from 0 to 1, then immediately jumps up to 5. Controlling the movement to get a level in between 0 and 5 is impossible. 4. The grip is just very uncomfortable for me. Im not sure what it is, but my hand cramps up all the time using this mouse. For some reason I also always end up right clicking when I hold down the left mouse button. Ive never had these problems with any other mouse.

With all the amazing reviews for this amazing price I was so excited to get a new mouse for work. After only having this for 4 days now I wish I could give this product a zero vs a one. I hate writing bad reviews; however i feel I had to on this one. I bought this mouse for work and I cant use it at all. It is not smooth or quick and it constantly gets suck. I tried changing ports for the receiver, tried changing batteries in the mouse thinking maybe the first battery was a dud, tried changing mouse pads cause maybe the one I was using wasnt suitable for some reason. Nothing worked. I cannot do my job at the pace I need to because this mouse doesnt allow me to. I ended up using another mouse my husband had as a spare which works great. I just wish I didnt have to use his and this one I bought for myself would work as the reviews stated. Very disappointed.

Time of delivery: Sometime around 11:00AM Time USB Wireless receiver broke: 11:15AM Time spent trying to extract broken parts from USB port: 45 minutes. This product is one of the worst things I have ever purchased. The USB port in my computer is now unusable due to the damage done by the USB wireless receiver. The holes of the USB portion for the wireless receiver pulled against the hooks of the USB port on my computer and the port is now completely unusable. This product was $9.99. Based on past experience, it would cost me $7.00 or more to return it with a shipping label. Thus, returning it isnt worth the $2.00. Stay away from this product. You get exactly what you pay for: Less money in your wallet

This mouse has lasted me over a year now. Ill say that over time, my opinion has changed from being satisfied with to ultimately disliking this item for a recurring lag issue. It regularly lags, often losing connectivity for short moments, causing the pointer to sputter around the screen erratically. I notice it cuts in and out frequently, perhaps upwards of ten times an hour despite a new battery. It does fit nicely and comfortably in the hand. Overall, you get what you pay for with this product.

1) Per product description, this mouse automatically goes to sleep if it spends long enough inactive, until you click a button to reactivate it. And the timers at that sweetspot where its short enough that you get annoyed when you forget its turned off already, but also long enough not to make any meaningful ripple in preserving battery life. 2) The buttons are wiiiiide and pretty sensitive. Its actually difficult not to accidentally right click things all the time without deliberately resting your finger to the side. 3) Battery life is short despite the above measure. I had a fresh AA last all of two weeks. 4) Removing and inserting batteries is an enormous pain. I have to pry out a dead battery with a knife! 5) Mouse wheel is touchy af. Sometimes youll scroll down/up and itll scroll itself back up/down a notch when you stop scrolling and the wheel returns to a resting position. 6) Having a button specifically to adjust DPI speed on the fly is not a bad feature to have built into a mouse, but there is no reason to put it where it is for how seldom itll be used.

Do not buy this!! I have been shopping on Amazon for over 5 years and have made well over 100 purchases. This is one of the few that I have actually been disappointed in! I didn’t really like the mouse when I first used it. It feels cheap and like it would not be very durable, but I was still willing to give it a chance. It works fine, but is also very uncomfortable. The ergonomic design does not fit my hand well. The first time that I tried to remove the USB piece from my laptop it broke! Now a piece of it is stuck and I will have to use a tool to remove it. My laptop is not an old piece of junk either. It’s only a couple of months old and nothing else has ever gotten stuck in it, so I’m confident that the laptop is not the problem. Overall, I obviously didn’t expect a top notch mouse for $10, but I still didn’t expect it to break so quickly.

This is not the worse mouse Ive ever used, but its close. Every 5 or so minutes itll just decide to stop registering movement correctly, and Ill have to deal with the pointer not moving at all, and then flying all over the screen. At first I thought it was just a bad battery (which are not included by the way), but after changing the battery the problems remain. Ive changed the dpi setting, and whatever the hz one is too, yet the problems remain. The most frustrating part, besides it being broken, is that occasionally itll work great. Sometimes itll be crisp and sharp enough Id say you could online fps with it. If it was always like that Id give it 5 stars in a hearbeat. The mouse itself is ergonomic, and the buttons are crisp with a satisfying plastic click, but neither of those trump that it just doesnt do what a mouse is supposed to. A good mouse should melt away, and let you interface with the computer without you even knowing its there. This one jars you back to meatspace far too often. *Edit* - I honestly couldnt stand it anymore. I bought a new logitech mouse, and Im returning this one as soon as it arrives. Everyone has been asking me why Im so angry. IM NOT ANGRY IM JUST FRUSTRATED BECAUSE OF THIS MOUSE! DID YOU KNOW CTRL-T OPENS A BROWSER TAB AND CTRL-W CLOSES IT? CTRL 1 - 7 WILL SWITCH THE CORRESPONDING TAB. USING THE TAB BUTTON WILL CYCLE THROUGH THE AVAILABLE LINKS ON A PAGE; SHIFT TAB CYCLES BACKWARDS. PRAY YOU NEVER HAVE TO LEARN THIS MANY KEYBOARD SHORTCUTS.

I have been very frustrated with this mouse. First I do have to say something positive. It does have a nice shape. I like the fast response. I thought it was going to be a real winner but I have gone through 4 batteries since I got it. I have gone back and experimented with laptop closed or left open. Nothing makes a difference. There is no auto off that works, and or mine is defective. This is very frustrating because it always fails right when I am focused and working on things, plus I have to carry batteries all the time to fix it. I purchased it almost 2 months ago so the window to return is closed. Like I said I thought maybe the problem was on my end, so I kept working on it. Ugg
