CRU WiebeTech Programmable Mouse Jiggler MJ-3 (Single Unit)

Just as advertised

This is an amazing little device! I purposely got this (MJ-3) because I intend to program it myself. Id like it to perform a series of keystrokes by itself every minute or so. If you dont want to program it, you dont have to. Out of the box, it will automatically move the mouse pointer a little bit every minute. I havent timed it to see if it is every minute on the minute or randomly within a minute. It works like it was described and doesnt allow my computer to go to sleep nor hibernate nor lock out nor have the screen saver turn on. Its like Im right there on the computer the whole time. Most of the time I am right there but I may not be typing or moving the mouse, but without this jiggler, my computer would lock and the screen saver would turn on. Its really small in size and, as the picture shows, comes with a cap. Even though it is tiny, I dont have any issues getting a nice hold of it and pulling it out of the computer. This has been an issue for me with some other dongles that are just way too small. I sorta wish that it had a key ring of some sort, but no big deal. You do not have to install any software to use this. All you have to do is put it in the usb port and itll work all on its own. Also, it doesnt show up on the computer as a jiggler or anything else like that; instead, it shows up as a generic mouse. If you do want to program this, you will have to install software that allows you to program it. But from what I understand, you do not need that particular software installed to have the programmed jiggler do its thing. This device is perfect for those that need to prevent their computer from going to sleep by randomly moving the mouse cursor very so slightly. I actually am on the computer almost 8 hours a day. I hardly ever notice the mouse move, but even when it does, its so small its hardly noticeable and doesnt affect my productivity in anyway.

Overall this is a helpful product for me. However sometimes it just goes haywire and my programs all freak out, change window size, bounce back and forth etc... that becomes highly frustrating. I wish it didn’t happen as often. I also notice my battery drop a little bit when in sleep mode when this is plugged in. Not significant, but it seems to always be working in the background.

This is a great product.

Overall a good product for people who use work or school provided PCs and cant control the power settings. It plugs in to any USB (type A) port and shows up to the PC as a generic mouse (so even if you cant attach a usb hard drive, this product should still work). It will work out of the box without any software or programming, and will move the mouse slightly every few minutes with this default program. If youre more technical and do want to program it, you will need to install software (available as an online download). Fortunately, it stores the program (script) on internal memory, which means you can program it on your own PC and then use it on another with no external software. The program to customize is pretty simple, using a graphical interface (sample image attached). No programming skill required, and its much simpler than something like AutoHotKey. Plug in the device, open the software, load the script from the device, and modify (or replace) as desired. You can control, the LED lights on the device (three colors), move the mouse, or simulate keypresses. One tip: the default mouse jiggler script moves the mouse enough that youll notice it (so you know its working), delete and replace with a script that moves the mouse 1 unit left, and then one unit right with no delay between the two, and youll never know its there while using your PC but still get the keep awake effect. The device is very small, enough so that it can be left plugged in on a laptop and still have the computer fit into a case, although the flip side of this is, since mine is a tight fit, its hard to pull out. Im giving it four stars because it costs more than many basic USB mice, I think at $12-15 it would be a better value. Still if you have the use case to need one of these, this seems to be the best one on the market right now.

It does exactly what it says it will do. Expensive, but for me worth it.

Worked like a champ!

This has changed my work day. I login in the morning and I dont have to worry about my screensaver locking me out until I leave at night. It is super small so it would be hard to notice. But on the flip side, its also really easy to lose. I would love it if it had a little hole in the cap so I could put a ring on it and keep it on my work lanyard.

Save yourself some time, use the 30 minutes I wasted researching and 4 days I spent worrying and just buy it. My IT department is a BIG corporate IT department and has the most obnoxious controls on our computers. This thing works no sweat. Im running Windows 10 on a Dell and didnt have to do anything except plug it into my USB drive. Buy it. Take it out of the package. Put it in your USB slot. Give your IT Dept the finger.

Best thing I could have purchased.
