Never heard of that brand before, I'd avoid it. That's quite cheap though.

my friend has one of their 27"s.. looksbadman.

180€ as if it is a good price? Got my W2363d for that much....

If money really is a concern just search excessively on the internet, you will find a good offer, like i did, my monitor is for about 300-350€ almost everywhere. Pro tip: look for stores which for a 120hz monitor is completely out of profile, mine was from a printer / toner store, it is even called "TonerWorld". Guess they exactly sold like 0 items for months, than decided to empty the shelves...

For Hanns-G it is absolutely a "bang for the buck" kind of brand, lowest prices in almost every category, so you can figure out their quality. Also just because a screen have 120hz refreshrate it doesnt qualifies automatically as a good gaming monitor.
