Better off saving your money for a quality brand like Acer or Samsung
Size: 24"/FHD/240Hz
If you were looking for a decent gaming monitor with a good refresh rate, you better keep looking. Honestly, I wanted to really like this thing. For $120, it ticked off a lot of great features for me: at least 120Hz refresh rate, 1080p quality, and some nifty reticule marks for FPS gamers like myself. And for a year I had no problems with it until a few days ago. The ability to control input's, power, and toggle the reticule features all lie on one singular button behind the monitor. Here lie's the issue; if that power button starts messing up, there is no way to control or turn on/off the monitor. This is exactly what happened on my unit; the power button/control went out and the monitor was basically useless. I contacted Koorui support via email, and all I got was a vague "Did you confirm the button is really broken" response. Replied back that I did, and the manufacturer has ghosted me. Basically, I HIGHLY advise you just save up a few $80 or $100 dollars and get a decent entry level gaming monitor. By going cheap with this one, you will just end up probably wearing out the power/control button and be left with an expensive paperweight. If you are DIY repair savvy, I am sure that replacing the power/control button probably is not that big of a deal. In which case, go right ahead as it is a decent monitor for the price. But with that said, having this thing break leaves you with basically no options to get it fixed and good luck trying to get a hold of Koorui for support. Sadly, this is a growing trend on buying electronic's here on amazon from smaller brand sellers.
*Update* So as of writing this review, I got Koorui to reach out to me. They would agree to replace the monitor for free, but I would have to front the shipping costs. They have their operations out in California, so if you live on the east coast then expect to pay around $40-50 for shipping for the monitor all the way out there (nearly half the monitor's value). I told Koorui that this just did not make any financial sense and they offered to refund me 50% of the monitor's value. However, they have yet to specify how they will send the refund, so I am unsure of whether I will see my partial refund when this is all said and done. So know that if you do proceed to get this monitor and need to return it past the 30 day return window covered by Amazon. TLDR: just save up an extra $50-100 for a big brand gaming monitor and save yourself the headache of dealing with all of this.

I feel fully enveloped in the work
Size: 34"/WQHD/1000R/HDR400
Changed my work at home experience. I feel fully enveloped in the work. I don't use it for gaming so can't comment on that. But for laptop heavy work days, this is a great experience.

Exceptional
Size: 22, Size: 22
Great quality and price. Monitors are exceptional. Would buy again without question. Screens are quite resilient, great picture. I bought three and use them in a multi Monitor setup for my work laptop, I needed something to view wireing diagrams and scan tool information qt the same time. If your a Service Technician looking for a multi Monitor set up would strongly recommend this Monitor.

Great product and great price
Size: 22
I think the negative thing I can highlight is the pixel dentist isn’t that high so it doesn’t look as crisp but this is a great budget option when you are in a hurry (like me) or simply need a screen that does its job. I use it for home office and it’s more than enough.
