“Tried the OP1 8k. Was a bit narrow. Got the XM2 8k and it’s honestly my favorite mouse I’ve ever had”— @bwb4449 on YouTube
“The op1 was too narrow and forced me into a more aggressive grip that triggered hand and wrist pain quite fast.”— PANO-ONAP on Reddit
“I bought an Endgame Gear OP1 8k, but i wish I had gotten something similar to the superlight because the op1 is wayyyy too narrow.”— Ltsdaa on Reddit
“Yep, I had 2 op18k with teh cables breaking on me after 4 months of usage on each”— WacistNagger on Reddit
“i have been using the op18k for about 10months on GX Speed mode and random clicks just started happening yesterday. clicks seem to register randomly when i rest my finger on left mouse button without pressing it. it felt like a switch durability issue.”— _fastpig_ on Reddit
“I was playing with op1 8k v2 and it bugged out and it did not register my click and then I tried to click again and it clicked and hold but I just tapped.”— zeluisvsc on r/MouseReview
“I have OP1 8k v2 but after testing it went back to box. ATK F1 / Hitscan Hyperlight better mouse for me. That shape is best I have tested. Nothing special about OP1.”— Nicotinisti on r/MouseReview
“I completely agree on the forward side button. Too far upfront and slightly uncomfortable to reach while getting support from the rear of the hump. 18x9 hand size”— Ambiciones on r/MouseReview
“Recently bought my 1st OP1 8K v2, but I had to return it because of a scroll wheel defect. The 2nd OP1 8K v2 I bought had the RMB raised way higher than left LMB.”— Beginning-Maize2899 on r/EndGameGear
“i just unpacked a new OP1 8K V2 and left mouse button isn't working. Tried the filter but eventually realized that it is some kind of mechanical problem with the button sensor not registering the click.”— dnizblei on r/EndGameGear
“OP1 8k the cable stopped working and before the cable died, I was constantly getting double clicking, sensor issues and the shell being so creaky like a cheap toy.”— gothtrance on r/MouseReview
“OP18K in my case is a claw grip, but only the tip of my fingers control the mouse, feels very non-ergonomic, and I have a bit of a hard time swinging that cord around”— peleh2 on r/MouseReview
Not complaints — practical notes from owners that didn't affect the score.
“I have the fastest latency mouse, the op18k, and can't differentiate it from any of my wireless mice (ulx, crazylight, f1 extreme, etc.).”— bearIyy on Reddit
“My OP1 is from one of the first batches and it has quite a lot of wear, but despite that there is only a slight flex in the clicks and some fraying on the cable fabric.”— emstan8 on r/MouseReview
“when I got both my OP1 8k and XM2 8k I tested them in human bechmark against my Razer Viper V3 and was unable to really conclusively see a difference. I was getting about the same scores with all of them”— TheFishStood on r/MouseReview
“Over an older mouse, absolutely. My previous mice were the aerox 3 and the basilisk pro (the first one) but over a different modern mouse, no not so much”— mad_dog_94 on r/MouseReview
“From what I have seen so far, they are quite equal when you pre-pressure the op18k Button. But the light clicks of the superstrike feel imo just bettet”— Silly-Championship92 on r/MouseReview
“yeah I think the only tangible advantage is the click latency improvement, I did manage to set a personal record on reaction time benchmark with it”— St0uty on r/MouseReview
“It makes a pretty big difference imo. Very noticeable when your games start to run and respond like shit because they don't support 8K polling.”— CircoModo1602 on r/MouseReview
“when I go back to my op1 I feel like I have to be more intentional with my clicks. Not a bad thing, just something I noticed.”— toastinato on r/MouseReview
